Section 7.5 (second half), Due Wednesday, March 14

The section for today was 7.5: Congruence and Lagrange's Theorem.

I thought that the most difficult part of this section was Theorem 7.30; its proof is very complicated.

I thought that it was interesting that mathematicians are trying to to classify all finitie groups up to isomorphism. That sounds like a really massive project. It would be really handy if they were able to do that.
