My current range for 5,313- ends at line 5916516, so I would guess sieving is about 15 - 20% complete.

I've run 700 curves on 613^509+1 with B1=250,000 and B2=116469998, which I believe completes this number to p30.

[Mon May 02 08:55:02 2005]
2^791+1 completed 843 ECM curves, B1=11000000, B2=1100000000

That should finish up 2,791+, at least to 45 digits. I'll pass this along to George.
