To calculate online the number of permutation of a set of n elements.

permutation online

The calculator allows to calculate online the **number of permutation of a set** of n elements without repetition.
A **permutation** of a set of n elements is an
arrangement
of this n elements.
The **number of permutations** of n elements without repetition is the number of ways to arrange these n elements, this number is
n!
(
factorial(n)
).

- Calculating the number of permutation of a set

The calculator can **calculate the number of permutation of a set** giving the results in exact form :
to calculate the number of permutation of a set of 5 elements, enter
permutation(`5`),
after calculation, the result is returned.

permutation(n), n is integer.

permutation(`4`), returns 24
