BTW, I'm going to move the above short exchange about 737*2^2382804-1 to our [URL="http://www.mersenneforum.org/showthread.php?t=6374"]Other Primes[/URL] thread.

Finally!!!!
 

Finally! I found a new prime for k=93:

93*2^580482-1 is prime! (174745 digits)

It is submitted and being tested by the prime database.

Kosmaj, now I finally found a large prime for k=93, I would like to release it and switch to other work. The reason for this is that it has lots of candidates to test (about 5000 per 100000n)

Templus
 

Congrats on a nice, large prime! :cool: I know that you worked on k=93 for quite a while. No problems if you want to stop testing. Just tell me the max exponent you tested, and have you checed all of them upto n_max. Please consider "donating" the remaining candidates to RPS. Thanks.

Templus- if you want to send me the remaining candidate file, I'd be happy to continue your work for a CPU-month or two. I can donate the remainder to RPS when I tire of the search.
