I've done 5500 curves with B1=44M, B2=192G on 3,575 c145. This adds 0.7116765 to the p50 and 0.1087279 to the p55 level.
I've done 5031 curves at B1=44M on 3,461 c157. This adds 0.65099 to the p50 level and 0.099456 to the p55 level. 4500 curves at B1=44M and 1960 curves at B1=110M on 3,461 c157. Adds 1.2079 to p50, 0.19926 to p55 and .01763 to p60. 7020 curves on 3,487 c222. Adds 0.915135 to p50 and 0.139882 to p55. 6420 curves at B1=110M on 3,545. Adds 10.4052 to p45, 2.03486 to p50 and .3586793 to p55. Alex Edit: these are done. Last fiddled with by akruppa on 20071214 at 12:00 Reason: Done.

Anyway, seems like the ECM gods are favouring your machines presently. Milk it while it lasts!

There are only 8 base 3 numbers left with exponent < 400. One of them is relatively easy (3,497+). Perhaps NFSNET might do them when they finish base 2 to 768 bits? OTOH, if one decides which numbers to do next on the basis of which ones have been been among the first 5 holes for the longest time, then the first few numbers in the 5 +/ table would be next.

NFSNET has already factored 3,491+. A few numbers just beyond the present limits of the Cunningham table have been factored as well. I kicked off a search for factors of small 3LM numbers and recent;y factored GW(3,729), which in Cunningham nomenclature would be 3,735. Personally I'd like to see the base 3 tables cleared out as I believe it is long past the time when they should have been extended to higher indices. That's why I put some effort into them. Paul

I've lined up 3,497+ for sieving tonight. Yep, I said tonight  the cluster will do all the sieving in 12 hours elapsed. Using half of the available cpus. It's a monster.

I would have expected a couple more factors..... At least we know that these numbers are really ready for NFS......
