This Demonstration shows a histogram counting the digits of BarnesG or Hyperfactorial in any base.

The built-in Mathematica function Hyperfactorial is defined as the product of elements in the self-counting sequence , so . The built-in Mathematica function BarnesG is defined as the product of the factorials of consecutive integers, . The number of digits in the elements of these sequences grow quadratically, as does the number of trailing zeros.
