It's just my opinion, but I think you should contact Nohara as he's reserved a 0.02M range already. Seems like he hasn't seen your previous reservation...

Thanks for letting me know, I will write to him.

I'm still working on both of them.
k=10813783 has been tested until n=690k, 255 tests until 1M left
k=27791 has been tested until n=300k, 2264 tests until 1M left
Both without new primes.

k=380630849 and k=59493015971 have both been tested for n=0-2,000,000. No primes found. The later k is of extraordinarily low weight (Nash weight is 5), so I'll continue it a little bit further.

Here are the numbers I have reserved and/or done work on:
131707 done to 1.6M, sieved to 3M. in progress
167021 done to 1M, sieved to 2M, in progress
171089 done to 1M, no further work planned (unreserved)
403993 done to 900k, sieved to 1M, in progress
9770317 done to 1.5M, sieved to 2M, in progress
13900807 done to 1.5M, sieved to 4M. Not active, but still reserved.

New reservation: 24384313. Sieving to 2M, LLR currently at 100k. I have new access to a small army of P2-class machines at work, which just screams out for sieving duty. Sieving a new k does the trick.

I am currently working on k=11639819, tested until n=400000, 660 tests until n=1M left

Thomas11 · 2006-03-09, 10:08

k=59493015971 is done to n=3M. I'll try to take it a little bit further...

403993 finished to 1 million, unreserved.

I have a question about one k I'm playing with.

For some time I work on k=2147483647 on my own (it's not on the RPS list of low weight k's). It is Mersenne prime (2^31-1). After I sieve range 350k-500k to 18G with NewPGen it remains 423 n values to test with LLR. It seems it is low weight candidate. I find two primes for this k, for n=97 and n=96001 (although I didn't test range 150k-220k, so it might be more primes in that region). I was thinking in testing this k to maybe n=2M, as after sieving I have relatively small number of n's to test.

But what bothers me is if somebody else was already done that. So, my question is does somebody maybe know where could I check if somebody test this k already? Or maybe if somebody is aware that someone else is working on the same k?

Kosmaj, already point me to the Top-5000 and where can be seen that Broadhurst discovered 2147483647*2^96001-1 on May 2000. So, it's possible he serached further. Any info on that is very valuable to me, as it will help me to decide will I continue to test this k or not.

Thanks for any input.

If a k is not part of any organized search, checking the top-5000
is about all you can do. Have you tried contacting the people who reported
primes for that k?

edorajh · 2006-03-18, 03:10

Yes, I send an email to dr. Broadhurst asking him how far did he test this k. Hope he will answer.
