12269^61-1 was being worked on by NFS@home, [url]http://escatter11.fullerton.edu/nfs/crunching.php[/url] says it is being post processed by M Vang (under the name 12269_61_minus1). A bit more co-ordination between Ryan and NFS@home would be nice.

This assumes Mike hasn't finished it and put the factors into factordb.

Has it been completely factored?

:redface:

That would be me.

I feed "todo" numbers to both Ryan and NFS@Home. I will check to see if there were any other duplicates.

Later - no other duplicates.[/I]
