1. I think the only tricky part about this section was the proof of theorem 8.1. I guess that wasn't even too difficult because I am feeling like I am grasping how to prove isomorphisms a lot better now that we have done the First Isomorphism Theorem a few times.
2. This section was relatively simple. I especially thought Lemma 8.2 was cool. I did not see the significance or newness it brought until I realized we were talking about ab=ba where a and b are elements within DIFFERENT subgroups! That is crazy! Before we only talked about elements being normal within a single group.
