===== Factorial basis =====

The [[https://en.wikipedia.org/wiki/Factorial_number_system|factorial basis]] is a number system in which the digits represent multiples of factorials. For example, $3:3:0:1:0 = 3(4!) + 3(3!) + 1(1!)$. Each digit must be less than or equal to the number whose factorial it represents. It is related to Lehmer codes and permutations.
