Base 13 prime found
Hi everyone,
one of my side projects has given me a large prime. I had noticed that there was no prime with base 13 in the top 5000. So I found one:
Primality testing 6710*13^1421431 [N+1, BrillhartLehmerSelfridge]
Running N+1 test using discriminant 11, base 1+sqrt(11)
Calling BrillhartLehmerSelfridge with factored part 100.00%
6710*13^1421431 is prime! (10738.7531s+0.0591s)
Other bases that need the same treatment:
base 7, 11 have +1 but no 1
base 13 has 1 but no +1
Base 14 has no entries.
Cheers, Willem.

PS what would be the most fitting subforum? I decided on CRUS because this is where i hang out.
