Difficult: For me, this section was pretty easy to understand, especially after making it through Chapter 6. However, I still have some questions. I was wondering what binary operations are allowed for groups. I guess I just am confused how to know how this operation is defined, or for that matter, how to define the operation. It seems like groups are a lot like rings, but I'm not quite sure what makes them different from rings. Is it just that only one operation is defined?
Connection: I like that in this section we are going back to something that seems more computational, and therefore a little less abstract. I am probably wrong though. I did like in this section how it talked about the composition of permutations. I like that this is very easy for me to follow and understand because I have been doing composition of functions for quite some time. I am hoping that groups will be a little more straightforward and simple to understand.
