By the way I've just found a utility called `pastebinit`, available in various linux package repository, that can upload files for you to a number of paste-host sites. This paste was created like so: pastebinit -i ~/server/ggnfs/C234_548557_43.log -t C234_548557_43 -a anonymous -b http://pastebin.com

I'll also take 77^128+1 cofactor for postproc

I'll try Fib(1327) from 15e.

pastebinit creates posts with a 30 day expiration. Note the number of days remaining at the top. I cloned your post and created one that doesn't expire:
