Great, although I think it might take you a little longer than you expect.

Group 11 is now completed. Included is a list of primes, ks with 2 primes and a list of remaining ks

Do you have any updates?

BTW, I have attached results for group 19. 7652 primes.

Yes, here's the result (I've completed on Christmas Eve but not yet time to compile/check ther results).

Attached are the two files with primes found for n=1001-10000 and the remaining k-values.

7631 primes found so 2369 k-values remain.

I've done the tests on a modified LLRnet server/client using PFGW.

I also changed the server-source to automatically remove all candidates of a k-value when a prime of that k-value was found.

The Log-file (also added) looks like this:

[2010-11-30 05:13:29] k=23638532, removed 484 pairs, 1294165 remaining.
[2010-11-30 05:13:29] 3660 remaining k-values.
[2010-11-30 05:34:33] kar_bon found prime 23991016*63^4920+1
[2010-11-30 05:35:15] k=23991016, removed 423 pairs, 1293742 remaining.
[2010-11-30 05:35:15] 3659 remaining k-values.

The problem (so not usable for an official version) is the number of candidates in the knpairs.txt-file (here at beginning about 1.5M!): sometimes (12x) it took to long to remove the k-values from the candidates-files, so those were tested further and perhaps a second higher prime was found.
