Taking S627 to 25k.

Take S803, S816, S844, S850, S853, S930, S953, and S1004 to n=200000. They need more sieving, so I pulled eight cores off of S6 to focus on that. Hopefully they won't need too much extra sieving.

R551
 

R551 tested n=100K-200K - Nothing found

Results emailed - Base released

R883 completed to n=250K and now 1k'er
Primes:
222*883^63471-1
224*883^72180-1
188*883^88589-1

Since my range of S6 will be done by Friday (with no primes :sad:), I will take S701, S702, S706, S736, S737, S740, S778, and S780. With the 20 single k bases I have reserved, I should find a few primes.

I will take S683, R611, R622, R688, R782, R833 to 200k.

Done with S683, R611, R622, R688, R782, R833. Results are in the mail.

Taking S574, S649, R773, R790, R850 to 200k.

Taking R580 to n=200K

Taking S643 to n=200K

Ignore Serge's post. He doesn't want to take it all the way to 200k after all :razz:

Update: R693 at 21,000 and still chugging, 82 k-values remain. Once it hits 25k I will unreserve, post primes, and rededicate that rig to my other base.
