[QUOTE=rogue;278928]Taking these based upon the file I posted weeks ago.[/QUOTE]

A couple of assumptions and a question:

1. I assume that you are talking about the monster sieve file for base 2 k<10000 sieved to P=100P (or some other huge sieve depth) by PrimeGrid.

2. I assume that you realize that these bases are at n=5.33M base 2. See base 2 k=5 at [URL]http://www.prothsearch.net/riesel.html[/URL]. Progress will be very slow.

3. Will you be searching all base 2 k=5 candidates for n>5.33M? If so, you might want to notify Primegrid or some other such "powers-that-be" if you haven't already done so.

I believe searching all base 2 candidates would be a lot more work than just bases 128 and 512. Base 128 would involve searching only base 2 n==(3 mod 7) [I think; you might check my math there.] and base 512 would involve searching only base 2 n==(0 mod 9).

1. I don't have the entire file, but John from PG will provide me with the list of n for k=5 that have not been sieved out.

2. Yes. I also have a list of n above 5.33M that have been tested, so I will not retest them.

3. No. PG is aware of what I am doing. I will provide them with residues when done. PG does not intend to take k=5 above 5M anytime soon, i.e. probably a couple of years away for them.

My final list is just over 1000 candidates to test between n=5.33M and n=6M. I want to got to n=6.3M, which would be n=900K for b=128 and n=700K for b=512. Going beyond 6M should wait for more sieving from PG, but since a number of tests above n=6M have been done (by ProthSearch users), that should only add a few hundred additional tests.

Done with R150 to n<=25K. 305 primes found, 122 [I]k[/I] remained. (I.e. there were more remaining [I]k[/I]'s at 2.5K, but less at 25K than those for S150.)
Results emailed. Base released.

Grueny,

Please provide us a status update on Riesel bases 214 and 253.


Thank you,
Gary
