We need 14e jobs
 

Anybody got anything to feed 14e?

While we live in interesting times, surely someone has a suitable job for factoring?

Would you like some entries from the Brent tables? If I read [url]https://www.slideserve.com/brant/from-fibonacci-and-base-12-factors-to-brent-factors[/url] correctly they have all been ECMed to T60 so are ready for SNFS/GNFS.

But I'm not sure how to test sieve it or estimate how many relations I would need.

Chris

I have a few of 5*2^n-1 form; I'll do some test-sieving today and get 'em posted.
