Calling all P-1 factorers, I'm in the process of creating a database of P-1 factoring data for all Mersenne numbers. I have not found any other database for this information available on the 'net. There is some data kept by Will that's available, but it only goes to M(169,991)... I am

I saw something similar once, out of hundreds of ECM curves that I've run. It happened on the curve being run while I adjusted memory limits on the program (Version 20.4.1, April 25 file date), if I recall correctly. Ken At 03:42 PM 5/25/2000 EDT, you wrote: I just got this in an ECM run on
