The factor group G/N is the group of cosets of a normal subgroup N. Here we construct two examples, one from S4 and another from U(9).

All of your videos are art. Literally the clearest explanation of abstract algebra I've come across.

I can definitely see these videos as being the critical "factor" in someone doing well in a group theory class!

Why do you have two (1423) in the table? One is in the second column, and the other is in the fourth column. And two (1324) in the third column?

What you do with a column of S4 (obtain a subgroup isomorphic to S3) is not possible with the quaternion group when you take N={1, -1}. I'm I wrong?
