The Mark of the beast, and the men who follow the beast of the earth will bear this mark to display their allegiance to the beast. It has been disputed by some scholars that certain numeric ciphers would translate it over to certain words, names, etc... For example, one of the more popular translations was Nero Caesar, and before that, Lateinos, etc...

"...And that number is 666."

Widely implied that it was 666 because it was an imperfect number to represent the impurities of man and their evildoings and sinful ways.

Read the book of revelations, at the end of the New Testament; it tells all about that, the seven seals, the apocalypse, Armageddon, Megiddo, etc...
666 is NOT the number of Satan. 666 is best described as a number of lawlessness, secularity, atheism, and sin - all things which many members of the human race indulge in. Emblazing the numbers "666" on your skin or affixing it to your screen name does not make you a Satanist - it makes you look like a fucking retard!

666 is an abundant number. It is the sum of the squares of the first seven prime numbers.

Since 36 is both square and triangular, 666 is the sixth number of the form n2(n2 + 1) / 2 (triangular squares) and the eighth number of the form n(n + 1)(n2 + n + 2) / 8 (doubly triangular numbers.)

There is no number whose value of Euler's totient function ΓΆ is 666, making it a nontotient.

The harmonic mean of the digits of 666 is an integer: 3/(1/6 + 1/6 + 1/6) = 6. 666 is the 54th number with this property.

In base 10, 666 is a palindromic number, a repdigit and a Smith number. A prime reciprocal magic square based on 1/149 in base 10 has a magic total of 666.

The Roman numeral representation of the number 666 (DCLXVI) uses once each the Roman numeral symbols with values under 1,000, and they occur in exact reverse order of their respective values (D = 500, C = 100, L = 50, X = 10, V = 5, I = 1).

I had no idea that the number 666 had any relavance to a legitimate mathmatical formula!
