14753*928^129-1 is prime. Somehow it was missed. I suspect that I used an older version of PFGW when I tested it. 3.3.4 states that it is PRP and prime.

Yes. I lost my main computer a few weeks ago. I now have a replacement. I intend to complete to n=25000, but I then need to look for potentially bad tests with PFGW and re-run them. I have about 100,000 tests left to get to n=25000. I estimate that will take about 50 days to complete. I don't know the effort needed for the double-check yet. I will have to resieve for 1000<n<15000 (ugh) on the remaining k. Hopefully I won't have to rerun too many tests.

Mark,

I'm going to need the results file for S842. There is no prime for k=47 and it is not shown as remaining. It's best if all of the results files are sent for any searches n>~2500.

Secondly, the k's remaining for S710 are incorrect. You have k=11 remaining. It should be k=10. k=11 has a prime.

I would like to respectfully request that if you reserve so many bases that you visually doublecheck and balance all of your primes and k's remaining yourself before posting your results. It takes me a lot of time to do so and follow up on problems. Thankyou.

OK, thanks. One note: You could go ahead and only reserve the base right now and wait until later to attach/send the primes and k's remaining for n<=2500. When you reach n=25K, then you can send those files plus an additional file of primes for n=2500-25K.

I'd like to take S588 from 25K to 50K (maybe more later; above 60K would make for a top 5000 prime).
According to vmod's new script, this is the highest-weight 1k conjecture still unreserved at n=25K.

Hi,
I'd like to reserve 74*533^n-1 for sieving from 25.000 to 1.000.000 for a friend of mine,
I told him from distributed computing and from this project, and he likes to see results in a short time, so we'll start with sieving *g*

paleseptember 2010-10-10 22:38

Rincewind,
I think it's a mistake to sieve so deep for 1 k. Perhaps taking it to n=100,000 (rather than a million) first, and then testing up to that limit.
Of course, other people may have a different opinion on the matter.

TimSorbet 2010-10-10 22:58

I agree with paleseptember: I wouldn't suggest starting with that much in the sieve file, do n=25K-100K or so instead. Definitely don't sieve to a depth optimal for searching all the way to n=1M. There's a very good chance you won't have to go that far, and that's over 9 million bits or 2.7 million digits.

I will show this as reserved up to n=100K. Sieving for n=25K-1M is unreleastic and a large waste of time and resources.

Serge,

Can you provide a status update of R580, S406, S676, S706, S798, S816, and S834? Thanks.

With Ian winding down the testing of 1k bases to n=100K and going through them quickly, I'll be following up on reserved 1k bases that are at n<100K quite a bit more often than usual in the future.
