222-digit SNFS completed with msieve

From the following link (by Greg Childers):
http://mersenneforum.org/showthread.php?p=115322#post115322
"The NFSNet factorization of 5^317-1 (SNFS difficulty of 222 digits) has been completed with msieve."
"...the runtime was just over 6 days"
Apparently this represents a real advance in speed of processing over the established suite for postprocessing large NFS sieve jobs. Thanks Jason (Papadopoulos)!

I'd just like to draw people's attention to the 'factoring' section of the mersenneforum (at the following link) - it has certainly made very interesting reading for me at times in the past...

Fermat number factorizations

Speaking of Fermat number factorization - this page:
http://www.prothsearch.net/fermat.html
lists the current state-of-play.
Note that only F5-F11 have been completely factored. The smallest Fermat number with no known factors is F14, and the smallest Fermat number whose compositeness (ie factorizability) has not been proven is F33.
[for additional/preparatory reference - Wikipedia article on Fermat numbers: http://en.wikipedia.org/wiki/Fermat_number]

Factorization of tenth Fermat number in 1995

From Richard Brent's page:
http://wwwmaths.anu.edu.au/~brent/pub/pub161.html
"We describe the complete factorization of the tenth Fermat number F10 by the elliptic curve method (ECM). The tenth Fermat number is a product of four prime factors with 8, 10, 40 and 252 decimal digits. The 40-digit factor was found after about 140 Mflop-years of computation"
