August 8, 1982 Page 9 of additions to the Cunningham Table is enclosed. Another of the "wanted" numbers has fallen. Congratulations to Mr. Suyama, who factored 2,362M. D. H. Lehmer sent me a long list of factorizations of 2^N +- 1 done by Naur in Denmark. Apparently, Naur has duplicated much of our work. However, Naur did 5 numbers which we didn't have. I sent him a copy of all our base 2 results. I don't know what method(s) he used. I finished the last C49 today. 12,153L and 12,195L will have to wait for page 10. I am doing three aborts (exits) now. Only five more C50's remain. I will work on them gradually! Keep the factors coming! Sam Wagstaff
