Factorial Number Base
Factorial Number Base
This Demonstration expands on Stephen Wolfram's Demonstration, called "Numbers in Various Bases", to show a fanciful number system that breaks numbers into blocks of size 1!, 2!, 3!, etc., with the number of blocks of size ! equal to the digit in the number's representation.

For example, "11" stands for one 2! + one 1! = 3. "321" is the largest three-digit number and is three 3!'s + two 2!'s + one 1! = 23, one short of "1000" or one 4! = 24.
Digits past 9 are represented by letters and the conversion function here stops where the letter is the last letter needed, servicing numbers up to about .
