That's scary how fast you did that. Would you like to do all of our bases <= 32 to n=100K? (I'll let you off the hook for bases 3/7/15.)

This gives CRUS its first top-10 Sierp base 25 primes. It took until the prime at n=67535 to crack the top-10 converted Sierp base 5 primes. That one has now dropped off the list with the n=71228 and 68611 primes now in 8th and 9th place.

I'll release S31. !!!

I have got much sieve work to do.

Darn it. He realized how much work it was going to be. lol

S 25 is done to n=100k

75k-100k 12 primes.

I release s 25 now.

I have a sievefile at 3.6T n<1M
Mail,PM if you like to have it.

Could you possibly send Gary and I the PRPnet results for this range so I can process them (as well as the original 25K-100K sieve file)? Thanks.

Base=10 (Sierpinski + Riesel) tested till n=460000.

R30 just passed n=200K for my three remaining square k's. No more primes.

I have actually sieved to 210K, so I intend to continue to 210K, then email residues and release.

Mathew did a sieve for R19 for n=30K-100K to P=150G.

Lennart did a sieve for S25 for n=100K-1M to P=3.7T. (!)

Both are now posted as zip files in ABCD (sr2sieve) format on the reservations page of the CRUS pages. They are ~2 MB and ~1 MB zipped so if you have a slower internet connection, you may have to wait a little while for them to pull them up. After uploading them, it took me 8 and 5 secs. respectively to pull them up.

If you decide to tackle a portion of these, you might see if you need to do more sieving first but both of the above are a very good start.

Thanks Mathew and Lennart!

Done, no primes; results attached.
