January 6, 1986 On Page 36 two "More Wanted" numbers were factored: Silverman did 2,518L C66 and Montgomery did 2,289- C75. In a computer file at Purdue I maintain the full Appendix C, which lists all composite cofactors in the book. The Appendix C which appears in the book gives the numbers up to 64 digits from the full Appendix C. Since almost all of these numbers have been factored now I have enclosed an initial segment of the current full Appendix C. It is updated through the bottom of Page 36. The EPOC is working on the last C61 now. Montgomery just sent me such a large number of factorizations that Page 37 already has 37 lines. He promises about 30 more in a few days. Thus, I expect to mail Page 37 soon. Keep the factors coming! Sam Wagstaff
