- Page 4, first line of Lemma 3: The inclusion should be k in K, not the other way around.
- Page 15, Line -7: Jk should be replaced by Ck, since Jk is
clearly infinite, since there are infinitely many primes. [Found by Jayce Getz.]
- Page 19, statement of Corollary:
The corollary should assume $n=[k:\Q]>1$, since when
$k=\Q$, we do have $d=1$.
- Page 19:
On p. 19, I think it should say D_r1,r2(1), not D_r1,r2(n), near the bottom. [Jayce]
