August 1, 1983 Here is page 22 of Cunningham Table additions. The C52's are finished. One of them, 11,61+, was a "wanted" number. I am working on the C53's now. Two of the C52's had a P26 for the second largest prime divisor. In these cases (3,477L and 5,129-) I decided to show the second largest prime divisor in full in the main table as well as in Appendix A. The first official update has been sent to the co-authors. It will list factors #320 to #565. Remember that I move to Purdue August 15. Probably this is the last addition page I will send from Georgia. Keep the factors coming! Sam Wagstaff
