Well, you've come to the right place.
Unless, of course, you need accuracy, in which case you're
screwed. Logic be damned, the factorials aren't good (as far as I know)
over ~10000! Either that, or they get a suspicous regularity (ie extra 3k
digits for every 1000 higher). I have no idea why.
Frank Pilhofer was the fourth (and most recent) person to respond to this page. He too has an interest in big factorials (and primes), and was kind enough to give me his source code, as well as a clever program for estimating them, using a neat sort of floating point-type deal. Everything seems to be perfectly accurate, except for the translation of "factorial." :)
The sysadmins here on Havoc are really cool, because they let me use ungodly amounts of disk space for these stupid numbers.
