Done! 4132590s (47.8 days). Once Marcel puts it up and I submit to Prime Pages, it should be the largest Mersenne Cofactor proven prime by a fair bit.

For the time being, since I want to wait on...

For 3^n+2, I did srsieve2 -n 1 -N 1000000 -s"27*3^n+2".
For 3^n-2, I did the same but with "27*3^n-2".

Similar results occur for -s"1*3^n+2" and fails to parse -s"3^n+2", as expected.

Edit: I...

It's likely that I'm very dense (as is standard), but I'm having whack-o issues attempting to run srsieve2 on sequences like 3^n+2 or 3^n-2. This might be along the lines of trying to use a...

I would like to bring my own personal attention, and perhaps yours, to section 7 - Prime Generator Properties. In particular, you mention for multiple paragraphs that the properties of prime numbers...

Are there issues with certificate uploading at the moment? I've tried, on three separate occasions, to upload a 37 MB certificate, with no indication of validation in status. Is there a weekly...

It's done! Precise count is 3934149s (45.5 days), although I had another decent power outage that had it not working for about a day. Seems like it saved the time stats correctly, though! Uploaded on...

I finished the next step in multi-base Sierpinski numbers, at least for my own discovery - a number that is Brier for base 3 (k*3^n is never adjacent to a prime).
I also did a little work to try to...

Cool! I'm glad to know that there's some proof for k for multiple bases and, knowing CRT, you could probably extend that to infinitely many bases - although I imagine one would have to be careful,...

Oh, are there solutions in there for 2, 3 that are Sierpinski for both bases? If so, I'd like to understand how those txt files show that!

I think I found a solution for b = 2 and b = 3, by doing some hacky work to combine covering sets. I constructed the covering sets such that I could share the most primes between them, and to fill...

Just in case it's missed elsewhere, I had a minor discussion/revelation about the "infinite set" problem that has a pretty trivial solution.

For bases of the form 15n+14, k=4 is Sierpinski to all...

Talking Numbers Sierpinski to multiple bases

Hello! This question errs on the side of not-number-theory, so I'll ask it here.

Given that Brier numbers (numbers that are Sierpinski and Riesel) exist and can be made by considering different...

Yup! 3970x system, for everyone else on the forums who may be curious.

I finished 3^45535+2 in about 23 days, though there was a power outage, so precise numbers were lost, unfortunately. The...

(51^4229-1)/50, (91^4421-1)/90 and 60^4663-59^4663 are all done! FactorDB finished with them and now they are recognized as prime.

Already finished the first one, should be verified on FactorDB soonish! The other two are spun up on my system and should finish in a day or two. Hope this isn't crass to start work pre-reservation!
