Still-Outstanding Errors

$\emptyset$

Errors fixed by October 25, 2011

I. GROUPS

pg 26: mentions two groups being "isometric" instead of being "isomorphic" (mid-page)

pg 28: Prop. 1.8.6 is missing the hypothesis that $H\cap K=\{e\}$

page 33:

- a 'P' appears in lieu of 'S' (third last line)

- '|SP|' appears where 'SP' should (third last line)

- instead of reading $H\subset S$, it reads H = S (last line)

pg 34: in Lemma 1.9.6, above the second appearance of the class equation for X, it reads S = |P| as opposed to S = P
