Reserving all remaining 11kers (at n=5K) to n=25K:
R648
R953
R977
S536
S654

Reserving a couple of (not all) 12kers to n=25K:
R766
S514

Also reserving S991 to n=25K.

S991 is a true heavy weight for such a large base. It is the only remaining base with a CK < 10K that has < 1 k remaining at n=5K for every 200 k's in the conjecture. (CK=5262; 26 k's remain at n=5K) To give an idea of how heavy weight it is, there are only about a handful of remaining bases with a CK < 10K that have < 1 k remaining at n=5K for every 100 k's in the conjecture.

Time to get busy...

R625 is done to 15K. Base released.
There are 106 k's remaining, but 12 of them are common with R25 (and some with R5, -- see R25). Resdiues are emailed.

1k base R533 has been released. Rincewind's friend sieved n=25K-1M to P=200G and released it without testing. A link to the file is on the reservations page. I'm sure it needs more sieving.

Ian, if you want it, here is one more 1k for you to take to n=100K.

I'll take it to n=100K. What's one more. LOL

Sierpinski 928 is complete to n=17K. 8 primes were found (check out the cluster near the end!)

Code:

4933*928^16010+1
24438*928^16188+1
18394*928^16370+1
14074*928^16377+1
22998*928^16555+1
20688*928^16920+1
12687*928^16933+1
9112*928^16985+1

Email sent, continuing.

(Edit: Well, it felt like a cluster! After 8 days without a PRP, to get those last three in quick succession....)
