I have not checked its validity, so reader beware. Nevertheless, this is interesting; but I wonder where people find the time to do such things? Tice Use it for IP, if you so desire.This may be the first known illegal prime. What folks often forget is a program (any file actually) is a string of bits (binary digits)--so every program is a number. Some of these are prime. http://www.utm.edu/research/primes/curios/485...443.html When written in base 16 (hexidecimal), this prime forms a gzip file of the original C-source code (sans tables) that decrypts the DVD Movie encryption scheme (DeCSS). See Gallery of CSS Descramblers (and its Steganography Wing) for more information. It is apparantly illegal to distribute this source code in the United States, so does that make this number (found by Phil Carmody) also illegal?
