Since 36 is both square and triangular, 666 is the sixth number of the form n 2 (n 2 + 1) / 2 (see (sequence A037270 in OEIS)) and the eighth number of the form n(n + 1)(n 2 + n + 2) / 8 (doubly triangular numbers, A002817.)

666 is the sum of the squares of the first seven prime numbers (i.e. 2 2 + 3 2 + 5 2 + 7 2 + 11 2 + 13 2 + 17 2 = 666 ).

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