Hello,

I reached to-day n = 7000475, no prime so far, continuing...

The file I am testing is now sieved up to 241 Tera and contains exponents up to
333,000,000

Regards,
Jean

[QUOTE=Thomas11;284264]k=59493015971 is now fully tested up to [B]n=10M[/B].
I'm stopping there and will take some other (even lower weighted) Ks instead.

If someone (Jean?) want's to take this k further, just feel free to do so![/QUOTE]

Thank you, Thomas, for your proposal!
I can now use a 4 core 64bit CPU to try to go further on this k value.
Do you still have a presieved file with exponents >= 10M ?
If yes I would be happy to start with it.

Thank you by advance and Best Regards,
Jean

Sorry, Jean, but I sieved the exponents only for the interval n=0-10M.

Kind regards,

Thomas

It is not grave, but would you send me the sieved file up to 10M, and the lresults file? may be I would make a double checking (after finding a prime...)

It took me a little time to dig out the old results files.
Please find them attached (including the sieve file).
Actually all below one million digits (n=3.3M) is missing.

Good luck for your search!

Thank you very much, Thomas!

I will keep these files carefully!
For now, I am only sieving for this k value, but sr1sieve-x86_64-linux is really fast : I have already overtaken p = 2T!

Best Regards,
Jean

I moved your discussion to a new thread called [URL="http://www.mersenneforum.org/showthread.php?t=16700"]Generating Low-Weight Ks[/URL].

k=9787 tested up to n=1M.
No new primes found. Releasing this k.
