The number of permutations means the number of possible orders in which a group of numbers or objects can be arranged without repetition.
The order of the selected objects is ignored. Each object may only be selected once in the object group, i.e. without repetition.
This example shows how many groups can be formed from the digits 1 to 3. It's the groups (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2) and (3,2,1). So six groups.
In the RedCrab Calculator, the Factorial function is used to calculate the permutation without repetition. Factorial calculates the factorial of the argument.
Example: Factorial(5)=120
