You're getting ahead of me with bases that don't require as many tests to find a Top 5000 prime. I have not put together a webpage yet as I've been busy with outdoor stuff. The weather this past weekend was fantastic here. I hope to get something in place by Memorial Day (next week Monday for those nonAmericans out there).

hi,
here are the results for carol / kynea b=28, n=1000 to 30000 (28^25201)^22 (28^5048+1)^22 (28^64921)^22 (28^65771)^22 (28^229601)^22 (28^24990+1)^22 (28^255281)^22

For b<=3000, in addition to b=640 (up to n<=40K) and b=1656 (up to n<=35K), there are three more b = {2264, 2482, 2634} that remain without known CK primes (up to n<=5100).
For b=2026, the smallest prime is (2026^5526+1)^22, the rest have a prime under n<=1000.

I'm starting to put together a website for this search. Take a look at http://www.mersenneforum.org/rogue/ckps.html and give me some feedback.

Update:
For b<=3000, there are However, for b=640, (640^44940+1)^22 is prime (252220 digits), so all b<1656 have at least one known CK prime! ___________________ ^{*} (2264^10098+1)^22 is prime Last fiddled with by Batalov on 20160529 at 07:28

lalera, did you only find Carol primes in those bases?
