Permutation is a type of arrangement studied in combinatorics, it describes the idea that a number n of elements can be arranged and rearranged in many different ways.
Enter a value between 0 and 500 to use the permutation calculator:
The permutation formula is represented by:
Pn = n! = n * (n – 1) * (n – 2) * (n – 3) ... 2 * 1
See below the example of the permutation of 5 elements:
P5 = 5! = 5 * 4 * 3 * 2 * 1 = 120
The permutation uses the concept of factorial numbers to calculate its results, see below other ways to represent such values:
P5 = 5!
ou
5 * 4!;
ou
5 * 4 * 3!;
ou
5 * 4 * 3 * 2!;
ou
5 * 4 * 3 * 2 * 1!;
ou
5 * 4 * 3 * 2 * 1;
