20.1.-20.2, due on November 25

Difficult:
    The corollaries in section 20.2 were straight forward, but I couldn't follow the group exponent stuff before it. I also had trouble following theorem 20.2. What did they mean let p=p^n? how can you just say that?

Reflective:
    I find it interesting that the classification of finite fields is so simple. Perhaps there is more interesting structure in the non-commutative case, but it's surprising how few conditions you need to severely limit the structure of what remains.
