I have found this strange and creepy piece of article from the Internet, I am sure it will give you the goose bumps to see how freaky it is.
The last book of the Bible, Revelation, brings up the number 666 as being the number of the beast connected with the end of this age and the coming of the Messiah. You will find the direct reference in Chapter 13, verse 18 of Revelation. Besides that cataclysmic reference, the number 666 has quite a few very interesting properties.
666 = 3^6 - 2^6 + 1^6
666 = 6^3 + 6^3 + 6^3 + 6 + 6 + 6
(Mike Keith mentions that there are only five other positive integers that exhibit this property...find 'em!)
666 = 2^2 + 3^2 + 5^2 + 7^2 + 11^2 + 13^2 + 17^2
666 = 1 + 2 + 3 + 4 + 567 + 89 = 123 + 456 + 78 + 9 = 9 + 87 + 6 + 543 + 21
Moreover, 666 is equal to the sum of the cubes of the digits in its square (666^2 = 443556, and the sum of the cubes of these digits is 4^3 + 4^3 + 3^3 + 5^3 + 5^3 + 6^3 = 621) plus the sum of the digits in its cube (666^3 = 295408296, and 2+9+5+4+0+8+2+9+6 = 45, and 621+45 = 666).
Incredibly, the number 666 is equal to the sum of the digits of its 47th power, and is also equal to the sum of the digits of its 51st power. That is,
666^47 = 5049969684420796753173148798405564772941516295265
4081881176326689365404466160330686530288898927188
59670297563286219594665904733945856
666^51 = 9935407575913859403342635113412959807238586374694
3100899712069131346071328296758253023455821491848
0960748972838900637634215694097683599029436416
and the sum of the digits on the right hand side is, in both cases, 666. In fact, 666 is the only integer greater than one with this property. (Also, note that from the two powers, 47 and 51, we get (4+7)(5+1) = 66.)
Mr. Keith also points out that if we assign numerical values for the letters of the alphabet starting with A = 36, B = 37, and so on, we find that the letters in the word
SUPERSTITIOUS = 666 !!!
From contributor James Watt comes the following: "Here are some other neat things about 666 I seem to have
discovered (since I never found any reference anywhere else). 6+6+6 =18 and 18 x 37 = 666.
Similarly, 4+4+4 = 12. 12 x 37 = 444. etc. In Roman numerals (and the Greek equivalents), which John would have used
to write them, it is DCLXVI, the exact sequential descending order of Roman Numerals.
Now 1/81 = .012345679012345679012345679.... Notice the 8 is missing. 1+2+3+4+5+6+7+9 = 37.
The other 'number of the beast' is called the vulgate number. It is 616. If 'vulgar' Roman numerals are used in
ascending order, vulgate Roman numerals 616 is IVXCD. The'L' is missing."
