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 [B][I]100[/I][/B] k's in the conjecture. :smile:

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.

Sierp 928
 
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

20688*928^16920+1
12687*928^16933+1
9112*928^16985+1[/CODE]

Email sent, continuing.

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