[math-fun] Prefactored large numbers

Can anyone please tell me if there's a source of prefactored large numbers (the larger the better) on the web? I'm looking for trends, so artificially manufactured numbers like the RSA-n's would not be of interest. Ideally, they would be in a consecutive range, like {10^50 + K : 1 <= K <= 10^7}, for instance. Thanks, Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
