Talking Prime for k=241489

Good news finally!

Found a new prime

241489*2^1365062+1 is prime!

Found and verified using llrnet and llr 3.5. Waiting for the database to confirm it. Though both tests were done on the same computer.

weight of k=150, so not bad
Rank=23
provers code =L101

Hope the next prime comes soon!

Citrix


PS: Lars, All the values for this k need to be updated but do not update the values for this k for my files, since all k/n pairs for this k have been sent to the LLR net clients, so I will be doing them in any case.

Great news!
Congratulations, Citrix!

Maybe this project becomes more attractive now. And new dat files speed up sieving.

Nice found!


I agree with Mystwalker, it's time to update the SOB.dat file.

Congrats Citrix!

(and all the sievers)

I think a prime for PSP was well over due.

Thanks to everyone involved in the project, especially the sievers as footmaster pointed out, I don't think I would have been able to find the prime, working by myself.

It is taking too long for primes.utm.edu to confirm the prime. It took me about 2 hrs to confirm the prime.

Footmaster, the llrnet server seems to be down, I am unable to connect to it for few days, could you look into it and also update your the files for this k for the candidates that have not been sent out yet.

I would also like to mention here that our next prime should be found much sooner. Since we will be switching to LLRnet 3.5, which is 4 times faster than the current version, in about a weeks time. Currently me and ltd is doing some testing to make a sure that it doesnot have any bugs, once this is solved, we should find several primes really fast, and you could be one of them to find them.

Secondly, I have been asked about a network sieve client. There is a way to use the exisiting client as a network client, but it is complicated and you will have to have an expertise in networking concepts. if intrested, let me know and I will help you out, in terms of setting the client.

How do you handle the incompatibility of residues?

keep track of which program was used for which residue and use that in the future for double testing.

Since the new LLR is 4 times faster, it might be better to do 2 double checks with the new client instead of using the old client.
