Perfect NumbersThere is a theorem that states that if
2^N - 1 is prime, then (2^N - 1) * 2^(N-1) is perfect. A perfect number is, by definition, a number that is the sum of all its divisors, excluding itself. The numbers 6 and 28 are the first two perfect numbers. By finding the 40th Mersenne prime, GIMPS also has found what must be the largest known perfect number, namely: (2^20,996,011 - 1 ) * 2^20,996,010 |

Yep, and its 13-million-digit decimal representation is at [I]([U]Think[/U] before entering this URL -- it's a 13 megabyte download!)[/I] http://mersenne.org/gimps/perfect6.txt.
(Why perfect[B]6[/B].txt? A: It's GIMPS's 6th discovery.) |

Here is a Bittorrent of that number:

Oh, yeah, Bittorrent - the latest newfangled thing I haven't gotten used to thinking of yet. Bittorrent. Bittorrent.
Next we'll have Byterapids and Wordgushers. Hey - Byterapids - see, there's a "tera" in the middle of it. "Tera" sounds like you're tearin' along at great speed. Say, where do I trademark this? (But what's an "ordgu"?) |
