So what's so interesting about the number 666, anyway?
LOL actually 666 is quite a fiendishly interesting number

.
-I thought everyone and their mother knew that 666 in roman numerals is actually all the roman numerals (except M) DCLXVI=666.
-"666" is the combination of the mysterious suitcase retrieved by Vincent Vega (John Travolta) and Jules Winnfield (Samuel L. Jackson) in Quentin Tarantino's 1994 film Pulp Fiction.
-Various conspiracy theories, including the novel The Da Vinci Code (Brown 2003, p. 22), have suggested that the glass pyramid at the Louvre museum in Paris is dedicated to the Beast and therefore constructed of exactly 666 panes of glass.
-the beast number is equal to the sum of the squares of the first 7 primes
2^2+3^2+5^2+7^2+11^2+13^2+17^2=666
-phi(666)=6.6.6,
where phi is the totient function.
-The number 666 is a sum and difference of the first three 6th powers,
666=1^6-2^6+3^6
-Another curious identity is that there are exactly two ways to insert "+" signs into the sequence 123456789 to make the sum 666, and exactly one way for the sequence 987654321,
666=1+2+3+4+567+89=123+456+78+9
(4)
666=9+87+6+543+21
-666 is the sum of the numbers on a roulette wheel
-A number x in which the first n decimal digits of the fractional part frac(x) sum to 666 is known as an evil number
-Wang (1994) showed that
phi=-2sin(666 degrees)=-2cos(6x6x6 degrees),
where phi is the golden ratio, which can be combined to give
phi==-[sin(666 degrees)+cos(6x6x6 degrees)]
-There are exactly 6 6's in 666^6
-666 is a repdigit and also a triangular number.
