Bernoulli and Euler Numbers

Some more recent news culled from the mersenneforum :)
http://mersenneforum.org/showthread.php?t=9841
advertising the recent revival of a couple of (related) factorization projects I had previously overlooked:
Sam Wagstaff (of Cunningham project fame) leads an initiative to find factors of Bernoulli, and Euler composites at:
http://homes.cerias.purdue.edu/~ssw/bernoulli/index.html
Note that Bruce Dodson has already found some good-sized ECM factors from these targets, presumably as a diversion from the main Cunningham project!
Some links describing these numbers:
