Here are the 4 new primes: (56^1698-1)^2-2 (58^1720-1)^2-2 (58^1734+1)^2-2 (58^2354+1)^2-2 I would like to search the bases to n=10K but I could not make cksieve work on my machine. So I just trial-factored in PFGW for the above. Every time I ran cksieve at the command prompt, I got a Windows error message as follows: Code: cksieve.exe has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. My machine is 64-bit, the O.S. is Windows 7, and there is 4 GB RAM. It is an Intel I7 running @ 2.67 Ghz. I have checked and even temporarily disabled my AntiVirus to make sure it wasn't being blocked. Has anyone else had problems running cksieve?
Hi Gary, thanks for joining.

I do not know why cksieve is crashing. This is the first that I've heard of anyone having such a problem. Does it crash immediately? What command line arguments are you passing? Can you build from source?
