Section 7.10, Due Wednesday, March 28

The section for today was 7.10: The Simplicity of An.

This section was pretty abstract. I thought that the proof of Theorem 7.52 was the most difficult to understand.

I think that the fact that was revealed at the end was the most interesting. It stated that If n>=5, then (1), An, and Sn are the only normal subgroups of Sn.
