Re: [ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine
Boom !
My biggest, and the biggest Gapcoin's Gap.
(length, not merit)
28168,C??,31.767181,Gapcoin,04-05-2021,386,1228769885602...
The previous one was a gap of 27666 @shift 896.

Craig also improved the record for 15122, so there are now only two gaps under 25,000 with merit < 25.
For those that aren't neck-deep in it, a 386-digit prime means Wizz used a shift of 1024 to get that seriously-improved merit.
The existing-soon-to-be-previous holder of that record was Dana Jacobsen and the gap was between primes of 502 digits in length - which is why Wizz' merit is higher, it's the same gap size but it's larger in relation to the digit length of the surrounding primes.
INSERT INTO gaps VALUES(28168,0,'C','?','C','Jacobsen',2014,24.3700,502,'637*1201#/18390 - 23308');
One slight thing that nags at me is that we're always submitting 'P' (probable primes) and it would be nice to upgrade them to 'C' (confirmed primes). I have asked about this and I'll probably get a response in due course. I used Dana Jacobsen's eccp-dj to do the checking, as well as PRIMO (just to find out what prime certificates look like).
As for the Mersenne Forum's Prime Gap Search group, they seem to be heading into a different space entirely: “I've got two 3M+ gaps in the offing.” - those have to be some seriously large surrounding primes.
