About the Number 2112 (two thousand one hundred twelve)

This nBAB about the number 2112 came about as a result of a nBAB about the number 31. The nBAB about number 31 prompted nBABs to be created for the numbers 80, 30, and 70 (in that order). The nBAB about the number 70 was BAB# 2112. This in of itself would not have prompted MathBabbler to create this nBAB, but 2112 was the name of one of MathBabbler's favorite albums when he was going to college. Note: The Canadian band Rush released the album 2112 in 1976.

What's a happy number?

   "A happy number is defined by the following process. Starting 
    with any positive integer, replace the number by the sum of 
    the squares of its digits, and repeat the process until the 
    number equals 1 (where it will stay), or it loops endlessly 
    in a cycle which does not include 1. Those numbers for which 
    this process ends in 1 are happy numbers while those that do 
    not end in 1 are unhappy numbers."
   [source: Wikipedia]

It only takes two iterations to see that 2112 is a happy number.

   2^2 + 1^2 + 1^2 + 2^2 = 10
   1^0 + 0^1 = 1
