I did not forget them. The prime gap that I pointed out for b=34 is still the largest for b<38 and n<=30K. This includes both sides combined for each base.

 2018-02-14, 10:16 #132 LaurV Romulan Interpreter     "name field" Jun 2011 Thailand 233528 Posts I was looking to those tables and saw that after 222 or so, the bases are not contiguous. I assume there is no search done for the missing bases, and the "higher" values just come from "people with a hobby" and not from an organized search. Because, unless I am not missing anything, I see no reason why the missing bases would not give primes. I think they do, and it should be no reason to jump from 222 to 228 (therefore missing 224 and 226) or from 2010 to 2026. Now, the introduction done, for a week or so we were looking for an opportunity to test the new "multi-threaded" tool from Mark (i.e. mtsieve). We picked CK numbers, and we picked the base 2018. As the current year, you know? We could not make the toy run in multi-threaded mode (this is subject for another thread), but we got hooked and let it run overnight to sieve (single thread) and test with pfgw with some batch file. In the morning we had few (small) primes, and pfgw was close to testing n=12k or so. Does it make any sense reporting it? Or we are really missing the point (again, it won't be the first time, hehe).
