Batalov, there are 56 bases 2<=b<=1025 remain (excluding perfect powers): 184, 185, 200, 210, 269, 281, 306, 311, 326, 331, 371, 380, 384, 385, 394, 396, 452, 465, 485, 511, 522, 570, 574, 598, 601, 629, 631, 632, 636, 640, 649, 670, 684, 691, 693, 711, 713, 731, 752, 759, 771, 795, 820, 861, 866, 872, 881, 932, 938, 948, 951, 956, 963, 996, 1005, 1015, with no known odd prime p such that (b^p1)/(b1) is prime.

No, I am not trying, 11 is of course a repunit prime, but I am searching the smallest odd prime p such that (b^p1)/(b1) is a (probable) prime. (but I don't have these programs)

Bases 711, 713, 731, 759, 771, 795, 820, 938, 948, 951, 963, 996, 1005, 1015 tested to 8500 (80018500).
No (probable) prime found. Also, bases 752, 861, 866, 872, 881, 932, 956 were already tested to 10000 with no (probable) primes found. Reserve bases 601<=b<=700 with no known (probable) prime of the form (b^p1)/(b1) with odd prime p (including 601, 629, 631, 632, 636, 640, 649, 670, 684, 691, 693) to 10000, using factordb.

Edit: does "using factordb" mean that you just put there the numbers and wait until somebody else (fdb elves) factor it for you? I think you are only trolling.... Last fiddled with by LaurV on 20161229 at 09:49

This Sweety439 is not just trolling, he just need all our attention :) When he got his thread ( and now something completely different) he was unsatisfied because none except him read that thread. And that is only thing that he dont need. He need to become center of Universe, at least. I assume that begin center on this forum is just start point to begin center of Universe . In mean time I waiting time when we leave this forum. Many before this guy left forum, and he will not be the last one: I am sure :)
I love team at this forum , and grateful for tons of help and time this forum gives to me! Go go mersenneforum.org
