S95 was getting worse and worse as time went by. Glad it's over.

currently at n=15k: since last report 190 new PRPs found. all proven prime with tp option.
i've inlcuded the updated page for Gary, too.

R96
Reserving R96 as new to n=25K.
There are only 298 k's remaining after the script run at n<=1K, the results are attached. Not too shabby. Going on to n=25K.

k=484 is eliminated by partial algebraic :)
Otherwise, all matches so far. Sieved to 1e9 and ...off we go. I'll report prelim status at 10K. Thanks, S P.S. 96 mod 97 for your "f generalizations", Gary! might the first one of the kind: Both k and b are 1 mod 97, so for the odd n's, divisible by 97, for evens diff.of squares.

You are correct, I believe this is the first one where a factor of 97 combines with algebraic factors to knock out some k's; both the "new" (factor 97 on even n's) and "old" (factor 97 on odd n's) kind too. After seeing the factorization last night as I was running it up to n=2500, if no one had taken it by Friday, I was going to take it because I was curious about it. It doesn't surprise me that it caught your interest. Gary

KEP is releasing base S63. There are 237036 k's remaining at n=1K. They are too numerous to show on the pages but are available upon request.
