3,766+ has been factored. It is the product of 66-digit, 75-digit, and 76-digit prime numbers. This is a new Cunningham project champion for GNFS. Let's now set a new record with 3,697+! |

Great! Huge amount of work, probably? How about updating the "status of numbers" page? (Am I the only person regularly looking at it?) TIA! |

In lieu of a much needed status update, 3,697+ was completed and reported to the Cunningham site during February as c221=p67*p76*p78
as compared with
for the previous record. That was
for the smallest factor. Current ecm-pretesting is fairly reliably finding p65's, using standards set in pretests for these nfs@Home gnfs's at c216, c221. Seems like one of these might have been found, with a bit more luck. Cunningham numbers currently reserved for nfs@Home include
If I recall, 3t60 =c. 15t55 was applied to these two record gnfs's. I was muttering at the time that adding an additional 2t60 to a completed 3t60 (for a c. t65) seemed too likely to be unproductive; but I've since gotten used to it (more or less!). -bdodson* (still 4th in total sieving creds; maybe 4th in ecm? after four consecutive records) |
