I have now completed Sierp base 3 k=10M30M to n=25K. k's remaining are shown on the reservations pages.

10 minutes attempt for Sierp Base 3 k=2930054:
2930054*3^25270+1 is prime! Last fiddled with by kar_bon on 20080614 at 22:44

OK, I've now had time to do a detailed doublecheck on all of your k's remaining for k=30M50M. In addition to the 5 k's that I found that can be eliminated from the last post, here is one more kvalue that can be eliminated: k=33040752 reduces to k=11013584, which has a prime at n=100378. This leaves 87  5  1 = 81 k's remaining for k=30M50M to n=25K. These will shortly be reflected as remaining on the reservations page for this krange.

Sierp base 3 is officially completed and checked to k=50M and n=25K. There are 209 k's remaining as shown on the base 3 reservations page.
There are 308 k's remaining if you include the k=100M120M range searched by KEP. Gary

I'll have to scratch my head on this... I think I understand now, but at 2:00 am I'm not too sure anymore (just got home from holidays) Update on 50100M, all is tested upto 10k now, and some 808 are remaining. I've started an overnight sieve, and will then go for a oneday prping, and restart sieving if it wasn't done far enough. (Hoping to find enough primes in that one day of course...)
