For megaminx, using the same logic in the video, a turn is 4 edge swaps, so you can swap the two edges, then swap edges twice somewhere else, which doesn't do anything, and there would still be one swap, so it is impossible to have to only have two edges swapped using outer turns on a megaminx.

@@nikotakai8796 yeah, if you learn how to solve it there shouldn't be any problems. Usually you only notice parity at the end and only have to do a corner twist which isn't much of a problem
AT TIMESTAMP 10:40 ) The number of *corner swaps* and *edge swaps* must be _both_ either odd or even on a *Megaminx.* The reason this only applies to odd-layered puzzles (-Minus the *Void Cube)* and not even-layered puzzles is because any puzzle with *centers* has this rule. An *A-perm, G-perm* or *U-perm* is possible because 2 intersecting *swaps* form a *cycle.* A *cycle* is formed when intersecting *swaps* of the same type of *piece (-Edge/Corner)* share a *last piece* (-This is why a *cycle* must have an odd number of *pieces.).*
Wow, this guy knows cubing. Also, the reason why on even layer cubes can have two corners swapped is actually because you also swap the inner pieces, which are edges. So you actually swap corners 1 time and inner edges 1 time.
j perm said he doesnt care about corners for the megaminx question. if we exclude counting corners, then it is definitely possible to have only 2 edges swapped on a 3 by 3 at least(example is T perm, J perm etc.)
Get some drinks and watch this with your friends. Everytime he says swap, everyone has to take a shot. I bet you'll only make it 'till 5 minutes or so.
I think swapping two pieces on the megamix is impossible for the same reason it's impossible on a 3x3. When you turn a face (which is the only legal move), you swap 5 corners and 5 edges. You can probably swap two edges and two corners, or two edges and two sets of two corners, or two edges and any swapping of corners that can be seen as an even number of corner swaps. This is my reasoning: When you turn a face, you do five edge swaps. With some manipulation, you can use this to swap two corners, then swap two other corners four times. This would give you two edges swapped while keeping the rest of the edges undisturbed. However, because this took the equivalent of five edge swaps, you need five corner swaps. It's impossible to have five corner swaps that cycle back to their original state, but you can swap two corners and leave the rest undisturbed. You can do this the same way you do edges, by swapping two with one swap and then using the other four swaps to cancel themselves out. I used the word "swap" 17 times in this comment.
Actually when you turn a face, you do 4 swaps of edges! Try taking the megaminx apart to swap 2, then the next 2, and so on. You'll only have to do this 4 times to move the edges around once
@@JPerm wow, can't believe I missed that. Then is it impossible to swap to edges no matter what? Since any sequence of moves you do will result in an even number of swaps, you can't get an odd number like 1. Thanks for replying btw, made my day :)
This was such a helpful video. I’m getting parities on my 4x4 all the time and I don’t know why. Previously, I thought it was meant to be “impossible”, but it turns out it is not.
Whenever I am unable to solve a weird state of my 4x4x4 cube I just scramble it a lot, start over and hope for the best. I’m not a speedcuber or anything but it is in my interest.
Know what, just ignore that comment. I couldn’t think of how to spell it so I just did that. And half way through of typing all that I thought myself as DUMB!
For the 3x3 edges... Imagine wanting to flip two edges. In order for the rest of the cube to be solved, you need to flip one edge, replace it, then RE-FLIP it. In an odd number of cases, you cannot reflip the same number of edges which leaves the cube unsolved, hence why you can only have an even number of edges flipped.
Not sure if you’ll see this comment, but I’ve been getting into speed cubing lately and watched most of your videos in a very short period of time. I love your content, it’s beyond helpful! I have a QiYi cube that somehow got the last layer corners swapped and seems to be impossible to be solved like you mentioned at 0:35. I’ve never had this cube apart, and I swear by that. I have no idea how it happened, and without taking it apart, there has to be a way to get it back, right? Thanks in advance if you see this. Keep up the great work!
Kinda late lol but this happened to me. It turned out to be center parity, where four centers were basically rotated around a slice layer by popping off the center caps so they looked right but were swapped causing odd center swaps which allows for odd edge swaps, and thus parity. U could always just disassemble the cube too, or swap the centers back
So I "knew" all of this... but hearing your explanation of it made it seem like something completely new and gave me that mind blown feeling. Best cube video of 2020. This will not be topped for the rest of the year.
he is definitely the best cubing youtuber out there... others just post cubing videos, but he also posts these kind of interesting videos talking about the overall nature of twisty puzzles
I have watched these videos for about a year, I never had a cube. Not even a 3x3 or 2x2 but I’m finally getting a go cube with some birthday money! I know a lot of techniques, ways to solve, and algorithms. I’m really excited to get my first solve!
learning, watching and reading before you pick up a cube is probably really smart. In the 90s, somehow I started receiving Golf Digest for free weekly. I read it for about 7 years before picking up a club. I decided to go play golf one day and shot in the 80s first time round. That's pretty amazing by the way.
No it isn't I literally solved a square-1 with no help when I got parity I remembered this video I knew I am at even slices then I counted my slices and solved parity on square-1 (+ I am Asian)
I actually figured a bit of this out without realizing in middle school when I was learning beginner method. I noticed that the amount of times uou had to repeat R’D’RD in the last step was always a multiple of 6 and I figured out how many repetitions each corner orientation required to correct and that it was always even.
On the void cube you also functionally have centers, they're just invisible and have multiple solved states Like if you ignore the centers on a normal 3x3. You'll have the same experience
Reasons why megaminx cannot have two esges swapped: 1: You cannot perform an 'm' move which means 4 edges move 2:there are 5 edges on one side and that means the edges cannot have a two edge cycle because there is 10 total pieces to solve in the last layer and most permutations have a clockwise rotation or two pairs of two edges swap and if that were to occur on a megaminx that means the one remaining edge needs to swap but it cannot. If you guys agree or disagree let me know and thanks for reading have a good day
The permutation group of the megaminx group (ignoring the normal subgroup of orientations) is a product of alternating groups, so clearly there are only even permutations of both edges and corners, even considered separately. So you can't even have a transposition of corners and a transposition of edges on a megaminx (as in something like a T-perm on 3×3).
I stopped watching Z3cubing over a year ago and I completely forgot that he changed his YT name to Z3cubing, it used to be legoboyz3. If you go to some of his older vids, he says legoboyz3 in his intro
This reminds me: Some kid at my school had just learned the 3x3, and this kid was getting super braggy about it, so I asked them if I couls scramble it for them, they said "sure go ahead", so I walked out of sight with the cube. I then proceeded to yank two edges out and swap them, creating void parity. I then gave it a good scramble to disguise my mischeif (obviously). I gave it back to the kid. Boy did I have a good time watching them struggle. It was hilarious
very late, but here's an explanation for why a megaminx must have both even edge and corner parity: turning a layer cycles 5 edges and 5 corners (4 swaps each) so parity for both is always even
I took the middle pieces of my GAN 356 X V2 to change the tensions and there were two corner pieces like the 3x3 in this video. They hadn't been twisted or taken out, the yellow was opposite white and everything was lined up perfectly and even when I put the middle pieces back on the corner, the pieces were still twisted. Very odd to say the least only it happened again cleaning out my Moyu WR M v9.
It’s called center parity and has happened to me before as well. Basically if u pop out 4 centers then rotate them once and put them back, everything looks the same and the color scheme is the same but there have been effectively 3 center swaps and no edge swaps with it like a normal slice move. And if there is an odd amount of center swaps and even edges then u often get parity.
@@MaffeyZilog I know. If u take out 4 center caps and put them in one spot over it causes parity on 3x3, due to an odd number of center swaps and even edges and corners
I love this cube theory type of video. I kind of want more of it, so if anyone knows something interesting, or even better doesnt know something interesting please suggest it to our mr j perm so he can spread his knowledge even more.
the absolute SPEED when you do the 2x2 swap thing is terrifying i feel like you could turn a rubiks cube into a weapon and murder me with it and use the cube to absorb all the evidence and then use the cube as a portal to escape into the fourth dimension so they never find you

A megaminx has 5 sides so each turn swaps 4 edges, therefore you can only have a even number of edge swaps and cannot just swap two edges.
its swaps five pieces not 4
I can't believe what a coincidence this is, I started computer science last week and learnt about even and odd parity in a binary register yesterday
For the megaminx question: No. Because when on Last layer, you can only have 1, 2, or 5 edges oriented and permuted correctly

They hadn't been twisted or taken out, the yellow was opposite white and everything was lined up perfectly and even when I put the middle pieces back on the corner, the pieces were still twisted.
Very odd to say the least only it happened again cleaning out my Moyu WR M v9.
It’s called center parity and has happened to me before as well. Basically if u pop out 4 centers then rotate them once and put them back, everything looks the same and the color scheme is the same but there have been effectively 3 center swaps and no edge swaps with it like a normal slice move. And if there is an odd amount of center swaps and even edges then u often get parity.
@@Cuber1771 You're missing the point. This happened to me on a 3x3 not a 4x4.
@@MaffeyZilog I know. If u take out 4 center caps and put them in one spot over it causes parity on 3x3, due to an odd number of center swaps and even edges and corners
@@Cuber1771 I get you now. Thanks!
I was like: 4×4 somehow keeps magically swapping pieces. Ok, this cube is definitely weird.
I love this cube theory type of video. I kind of want more of it, so if anyone knows something interesting, or even better doesnt know something interesting please suggest it to our mr j perm so he can spread his knowledge even more.
I can’t swap 2 edges on a megamix because I don’t have a megamix !!!!!
Nice vid more of this kind

No because megaminx is 3x3
Heckmate
This is some good wisdom
Can we just acknowledge the fact that he never puts in any ads?!!?
He does your prob just on an apple product
Say hello to speedcubeshop.com
the absolute SPEED when you do the 2x2 swap thing is terrifying i feel like you could turn a rubiks cube into a weapon and murder me with it and use the cube to absorb all the evidence and then use the cube as a portal to escape into the fourth dimension so they never find you
The word "swap" doesn't sound like a word anymore and has lost all meaning.
I really like the cube theory vids. Can't wait for more
Me: I don’t know what this means TH-cam gave me this HELP ME
1:01 "So I know an algorithm that can solve these two"
1 second later: Cube.exe has stopped working.
Im early let me tell a joke
My WCA results
Same lol
Thank you so much for the taiwan chinese subtitles!
1:36 and one is not a multiple of three
1/3: *am I a joke to you?*
Your videos are awesome!
Im literally so confused
Yeah, I understood almost nothing in this video lol
TheCakeMuffinCrew He did a horrible job of explaining
Fake Seattle Sounders FC no. you did a terrible job at listening :)
You need basic cubing knowledge to understand this
