Indeed, and I encourage you to be sitting down when you read this next part :
Metcalfe's Law is fundamentally linked to triangular numbers (triangle... Sound familiar?) and guess what else is a triangular number? Yes. Gasp you should.
666. The number of the beast. From wikipedia:
666 is the sum of the first 36 natural numbers(i.e. 1 + 2 + 3+ ... + 34 + 35 + 36 = 666), and thus it is a triangular number. Notice that36 = 15 + 21; 15 and 21 are also triangular numbers; and 152 + 212 = 225 + 441 = 666.
In base 10, 666 is a repdigit (and therefore apalindromic number) and a Smith number. Aprime reciprocal magic square based on 1/149 in base 10 has a magic total of 666.
Dude. A magic total. I didn't make that up.
That's fucking science.
