Erm..., yeah :)
As I was deleting them from my sieve:

oh darn. already had that one...
oh... that one too...
oh no, another one...
gee... this can't be!
Oh NO :)

Ah well... at least you got one down :)

Are (hopefully new) primes.

Max, is that you and that higher-level math again? Yesterday, it was putting n=30900 lower in the descending prime list than n=30200. And now this?!

What's the world coming to?

I changed the 1st post.

See my web pages now for a way to help find former primes. I've now created a separate page for all Riesel base 3 primes for n>25K. On the Sierp side, it's n>70K with a list for n>25K coming in the next few weeks. it wouldn't have helped here since both were reported at about the same time but it should help if they're reported a day or 2 apart. The pages will be updated in a little while.

Whoops.

Thanks for fixing that, as Carlos said I must have been tired or something.

Max

P.S.: Gary, would you mind taking care of all the recent primes in this thread? This recent batch seems to be especially confusing in regard to which primes are lower, higher, and whatnot, and as it's getting a little later in the day I'm not sure I can be trusted to get it right.

lol, oh you can get it right I'm sure. I'm sure I'm annoying you a bit with my pickiness.

I'll get it updated a little later tonight.

Thanks for the large amount of help you've already done.

This has been a difficult effort to administer. Likely we'll start future k=100M range drives from about n=40K or so. Too many small primes and too many k's makes it difficult when people are testing such a wide n-range. It's relatively easy for one person to run on several cores. The Sierp team effort that is at n=87K is more my speed now.

I think someone had suggested a team effort starting from n=10K on a very wide k-range previously. As tough as this is, you can see how difficult THAT would be!

This is where my page of primes for n>25K came in extremely helpful.

Max, you're in luck here. Just to let you know that I spread out the pickiness fairly amongst everyone, I get to give someone ELSE a hard time this time.

Micha, since when is 27596 > 31448? (lmao) I think there's some new math going on in the community that I don't know about.

For historical reference

, here are the smallest primes on all of these k's in order of the way Henry listed them:

34640024 29244
87236956 29285
58220776 29382
8560054 27596

All k's with primes have been removed from all appropriate files. I've also added files up to n=50K.

See a web page that has all Riesel conjecture base 3 primes for n>25K here.

12319264*3^41472-1

44956796*3^41899-1
Is prime.

41-42 complete.

Taking:
42K-43K
43K-44K

I believe there has recently been a reversal in the fabric of time, which, obviously, must lead to the fact that
a) 27596 > 31448
or b) More people are asleep while typing on fora

You take a good rest Gary, and keep at it :)

Edit: I have now 298 k's left in my sieve; updated to post 77
