7.2

1. What was the hardest part of the reading for you?
I'm honestly kind of confused by some notation here. Mostly with corollary 7.9 on the part that talks about how "that is, |a|=<|c|..." I'm confused because doesn't |a| mean the size of the group? Like.... shouldn't this be |G| not |a|? That is what I"m most confused about right now.

2. Embarrassed
Well, that was really the hardest thing for me, but as I was looking around for what I could write here, I thought "Find the earliest use of |a| and see if you can figure it out." Well, then I ran into the part where it talks about it and now I'm embarrassed that I didn't see it the first time through. It looks as though |a| is the order of a, which is fine, but I just get so darn confused by the crazy use of notation all over the place! Oh well, I guess I'm just a goober.
