7.1 (part 2), due March 7

The rest of 7.1 wasn't too bad.  I recognized a few examples from our class discussion on Friday.  I thought the dihedral groups were pretty neat.  I thought it was really interesting how abstract algebra could apply to geometry.  Some of the examples towards the end of the chapter were hard to follow the first time around but after looking at them again, I was able to get the jist of them.  I'm still a little fuzzy on the general linear groups but that will probably be ironed out in class.
