A new ECM factor:
675353281583190606094335948707995673045348275372668260771  10^209 + 3^209 I have to check ~10 composites first before I find a factor with B1=11e7. So I guess the remaining 500 composites are thoroughly tested.

I'd like to have a reasonably accurate estimate of how much ECM work has been done in total so that the server can allocate close to optimal tasks. Paul

Ha ha, didn't know, I am not a fan of "5 pages large emoticon", and never scroll that list so down. That doggie looks great, but is too big, I can't sign my messages with it Thanks anyhow, I will try to make some use of it...

We'll definitely hit 500 since 5^346+3^346 is almost complete. Delayed due to a power outage at work over the weekend at work, and the UPS died before the emergency generator was cranked up....

5^346+3^346 is complete and reported to Paul and the factoring database.
