I make that 41 new factorizations in 20 days, which is a pretty good average rate.

Thanks to everyone who has contributed, including those who have not yet struck lucky with ECM. You'll get there eventually!

Now for the new work done since the last update:

I make that 51 results, a higher productivity than the previous period. At least part of that arises from fivemack's old machines being set up as ECMnet clients.

Keep up the good work!

If anyone, especially Xyzzy, is wondering why 14682 is so wildly out of sequence it's because I found that he had not been credited for that factor around 18 months ago. Rather than insert it into its proper chronological sequequence, which would have required extensive re-numbering, it's in the current progress file. Better late than never.

Sometime in the next few months I hope to put all my factor tables into a custom database so that updating the tables becomes less error prone. I'm torn between hoping that it will clean up the current information and hoping that it will correct presently overlooked errors.

The ECMNET server running at 83.217.167.177:8194 is now allocating tasks with B1=3M, optimum for finding roughly 40-digit factors.

Thanks to everyone who has been working on these numbers.

FYI your link to the 2011q2 results file is broken. It redirects to 2010q2.
