I’ve been talking about finite groups of small order in my class lately. In particular, examples of abelian and nonabelian groups and the notion of isomorphism classes of groups with a given order. I’ve written up some notes on the proof that all groups of order are abelian, and some notes on the isomorphism classes of groups of order . Also, I wrote up some notes on using a bijection of sets , where is a group, to define a unique group operation on such that is an isomorphism.
