Belphegor’s Prime is a unique number. First, it is a PRIME number. It is also a palindrome. It contains the number 666 in the middle, and is then surrounded on each side of that with THIRTEEN (13) zeroes and a numeral 1. This means it could also be written as 10(13)666(13)1. This number also contains a total of 31 digits, which is yet another 13 (backwards).
