The number eleven is the fifth prime number (contrary to popular belief, the number one ( 1 ) is not a prime number).

The base numeric number system lends itself to some interesting peculiarities as relates to the number eleven.

Base 10 for example:

(2 digits) 11 x 11 = 121

(6 digits) 111111 x 111111 = 12345654321

(9 digits) 111111111 x 111111111 = 12345678987654321

Base 16 (hexadecimal) for example:

(2 digits) 11 x 11 = 121

(6 digits) 111111 x 111111 = 12345654321

(9 digits) 111111111 x 111111111 = 12345678987654321

The event normally occurs once in a human lifetime, unless you live to be at least 100 years old. It last occurred on 11/11/11 (1911).

Rick, you have way too much time on your hands!!!
