Factorial number system. In combinatorics, the factorial number system, also called factoradic, is a mixed radix numeral system adapted to numbering permutations. It is also called factorial base, although factorials do not function as base, but as place value of digits.
Factorial of x. The factorial of a natural number x is the product of all positive integers less than and equal to x. For example 5! = 5*4*3*2*1 = 120. SpeQ can also calculate the factorial value for positive, non-integer values.
