Sierp base 31 is FINALLY complete to n=25K; 23 primes found for n=24K-25K.

A nice round 1111 k's remain as shown on the base 31 reservations page.

I'm glad that's through. The base is released.

All bases < 35 conjectured at k<1G on both sides are now complete to n=25K. :smile:

I'll attach the n=10K-25K primes to this post after I get back from a business trip; likely this weekend.

Xentar sent me results for S17 on Jan. 26th that showed he was at n=500K. AFAIK, he is continuing with it but I'm in the process of verifying that.

Update
 

sierp-b17: one k remaining, n = 520K
sierp-b19: 990 k remaining, n = 34k

Continuing :smile:

Xentar,

Just to confirm: You have fully searched to n=34K; correct? The primes just stopped at n=33630.

I did a full rebalancing of the k's that need primes and primes that we have so far on this base and found a couple of errors on my part:
300514*19^8603+1 is prime
537604*19^12207+1 is prime

These k's had been listed as remaining on the reservations page. Assuming that you still have them in your sieve file, you can remove them. Sorry about that.

After you remove them, you should show 988 k's remaining as of your most recent batch of primes at n=34K.

Rechecked, proven and removed. Thank you.
That makes 987 remaining :smile:

Sierp base 9 is at n=400K; nothing to report; continuing

I'm extending the reservation to n=750K. Max will assist for n>500K.

I have double checked the entire base for n<=215K and for n=300K-360K. No problems found so far. Continuing until the double check is complete for all n<=360K.

2036*9^n+1 up to 360k. No prime.

Results 350k-360k sent to Gary.

Status report
 

Base=10 (Sierpinski + Riesel) tested till n=410000.

Sierp base 9 is at n=500K; nothing to report; continuing.

Max began assisting for n>475K.

I have now double checked the entire base up to n=360K.

Riesel base 22 is complete from n=300K-400K, no primes; results attached. I'm keeping this base reserved to an undefined maximum n-range as before, though it's temporarily on hold since my quad is currently busy helping Gary out with Sierp. base 9. We'll stay on base 9 as long as we can stomach the test times, so it may be a few months before I get back to base 22, though I do intend to return to it. In the meantime, though, if anyone else wants it really badly (and can sustain at least as much resources on it as I would, i.e. one quad), I'll release it. :smile:
