Is unreserving the Base 19 Sierpinski at n<=12320. Here is the primes that I've found between n>12000 and n<=12320:

Code:
6366*19^12080+1
162246*19^12130+1
32716*19^12136+1
55656*19^12194+1
351846*19^12012+1
314886*19^12022+1
337254*19^12143+1
231438*19^12146+1
282136*19^12188+1

751966*19^12244+1

A total of: 20 primes

Regards and bye for now, until I complete the Riesel Base 3 (2-3 weeks at most)

?? Kenneth, I appreciate your contributions but I'm finally out of patience. Moving, switching, and reducing reservations is fine for a little while until people understand the length of time it takes to complete things but it has to stop at some point.

But it's become more than an understanding of the length of time to complete things. You keep saying different things from one day to the next.. In another thread just today, you said you're going to do Sierp 19 and then do Riesel 3 at about the same time, now you're going to complete Riesel 3 and unreseve Sierp 19 even after saying that Riesel 3 involves 'too much manual work'. In another paragraph, you're saying you're going to do Sierp base 3 but don't tell us what range. Previously, you said you'd take bases 22 and 23 to n=1M and then stopped and sent me files sieved to P=5T, which I greatly appreciated at the time.

KEP, what's it going to be? This must stop. To be a contributor to any project, you must complete what you reserve (or even reduce a reservation in the case of not being aware of the length of time it takes) and stop moving around. It's all up to you. Some (perhaps most) moderators may have more patience, a few may have less, but for this moderator, I've run out.

Please tell me what are you going to complete and stick with it. If you're done with Sierp base 19, we would really appreciate a sieved file for the remainder but that's up to you. But I must ask you, why give up when you were so convinced you could take Sierp base 19 to n=100K in 200 days? I was hoping that you would prove me wrong on the 40 CPU-year estimate.


Thank you,
Gary

I have moved posts about work on bases > 32 that are not power of 2 to a new thread here to keep this thread from being bigger than it already is.

Aloha,

I've completed the search on base 25 riesels until n = 20,000. I am starting a new sieve until 25,000.

Laters, Willem.

Default Base 19 riesel update

Aloha everyone,

in the last few months I found a bunch of primes while taking my range to n = 30,000. I've just tested them again with PFGW and they hold true.

Thanks for the huge amount of work on this base Willem.

Are you now complete to n=30K?

Oh, I see I forgot to do the companion post to the reservation thread. Yes, I reached 30,000 and I have stopped there. All yours for the taking.

Enjoy, Willem.
