- In this video, we show how to express elements of the symmetric group S_n as products of 2-cycles (i.e., transpositions), and this allows us to define even permutations and odd permutations. From this, we are able to describe an important subgroup of S_n consisting of the even permutations: the alternating group A_n.
You have an honest intention of teaching.
Therefore, you teach well and it is natural.
Thank you.

Sir ,what a effective simple classes.deserves more reaches ..from India,kerala.thank you so much sir
This guy is such an amazing teacher!!!!!!
I am two weeks in to an online course in Abstract Algebra and thus far have had almost no idea what is going on. This is exactly what I needed!! Your videos might make all the difference in helping me not fail this course, I am extremely grateful.
Wow, your are truly a gifted and dedicated educator.
Thanks for sharing! The video really helps to visualize and recap everything when one comes out of abstract algebra class.
Thanks a lot sir for such a easy to understand explanation. You might have just saved my final grade.
Simplest way to understand about symmetric group and alternating group. Thank you 🙏
Truly appreciate your will to teach :)
Underrated
Every time you do your little nervous laugh like at 9:58 it
makes me feel exposed for not getting it haha
Love it ❤❤ ......sir u teach with love and passion thats what we need......wooowww❤❤
