A friend recommended me this channel. He has watched every single video on this channel over a span of more than a year, and I can definitely see why. I am trying to do the same, and will definitely watch the important videos (Sylow groups for example) multiple times, to get a better picture.
The lattice of subgroups for the rotations of a tetrahedron seem wrong? Im not sure that it has subgroups of order 2 since it is isomorphic to A_4 which itself clearly does not have subgroups of order 2. Please let me know if I am saying something stupid.

Thanks for all the great content you have uploaded :)

(13)(24) generates a subgroup of order 2
so does (12)(34) and (14)(23)
@Fractal Of course they do I’m an idiot 😅, thanks
