Returning 280 - 285 T, 9 factors found. If anyone is interested, this means the sieve has progressed past 2^48. Last fiddled with by lavalamp on 2008-09-22 at 15:34

I've also updated the attached sieve file in the first post. All factors to 305 T have been removed from it, and also the algebraic factors now (of which there were 411). There are 14,169 candidates remaining in the sieve.

 2008-12-01, 03:59 #54 lavalamp     Oct 2007 Manchester, UK 2×3×227 Posts Returning 330 - 335 T and 335 - 340 T, 6 and 4 factors found. Taking 340 - 345 T and 345 - 350 T. Since there seems to be a lack of interest in this, I think once I get to 350 T I'm going to suspend it. Obviously I'll keep all the factors found and the latest sieve file safe. Perhaps when LLR tests of 10m digit numbers run in hours instead of days there will be more interest.
