I was confused about the statement that if K is a Sylow p-subgroup of G, then so is x^-1Kx. Perhaps this is related to confusion about 'the image' of something. Were they just trying to say that a subgroup and it's image are isomorphic?
Reflective:
I noticed that Cauchy's thm was in this section - so we must have done it early in class and not with section 8.3. Why is that?
