Apocalypse Number

A number having 666 digits (where 666 is the beast number) is called an apocalypse number.

The Fibonacci number F_(3184) is the smallest Fibonacci apocalypse number (Livio 2002, p. 108).

Apocalypse primes are given by 10^(665)+n for n=123, 1837, 6409, 7329, 8569, 8967, 9663, ... (OEIS A115983). The smallest apocalypse prime containing the digits 666 is 10^(665)+166657 (Rupinski).
