*[Actually I think (44) is correct as stated. Exercise 52 has been fixed. -T]*

*[Thanks for the first correction. Regarding the second: we are using the “G” portion of 29d rather than the “F” portion. -T]*

*[Now corrected – T.]*

*[Now fixed – T.]*

Also, in the proof of Theorem 8, the first instance of Theorem 7 should instead be Theorem 6 and I think the second instance of Theorem 7 should be Theorem 5 and the last instance of Theorem 7 should instead be Theorem 6.
