February 19, 1983 Here is page 16 of Cunningham additions. I guess Mr. Baillie is not the only one factoring. Correction: The last 4 digits of #379 should be 3441 rather than 3341. (Page 15). Enclosed is a list of people who receive this update. Please inform me of anyone else who should receive it as well. Also, please tell me if you want your name removed from the list. Also send address corrections. Mr. Baillie has found (#431) the first prime > 10^25 which (almost certainly) must be written in full in the Cunningham main table. I suppose I should put it into Appendix A as well. It has 26 digits. During the past month we added many proofs to Appendix B. Some I got from Dr. Brent and Mr. Suyama last year, and some I did myself. They will be published. Keep the factors coming! Sam Wagstaff
