Reserving S433 to n=25K.

gd_barnes · 2010-09-14, 23:39

S315 is complete to n=25K; k=278, 550, 836, & 1390 remain; highest prime 1186*315^18580+1; base released.

Not bad for CK>1600 and base > 300.

Reserving R370 and S376 to n=25K.

Reserving S443, S447, and S493 to n=25K.

Just to confirm: This is sieved to 1 trillion. Correct? Not 1 billion, which is what is shown in the file.

I always attempt to make sure that the sieve depth shown in a file posted on the pages is correct.

After reserving R315 officially (see post #562) this time, I saw it was done in the meantime to n=25k!

I'm just sieving k=64 and 400 to n=100k.
k=552 is done to n=100k, no prime found!

Gary,

That is correct. I used srsieve to 1e9, then sr2sieve to 1e12 the last factor was 997462712503 | 64*425^85675-1.

S257 complete to n=100K, no primes. Results for 50K-100K attached; releasing.

The following are complete to n=25K and released:

S376; k=222, 246, 298, 463, & 477 remain; highest prime 157*376^20880+1
S433; k=22, 108, 118, & 264 remain; highest prime 106*433^21228+1

Riesel 353 the last k, tested n=25K-100K. Nothing found.

Results emailed. Base released
