Enter the total number of objects and the sample size to calculate the number of possible permutations. A permutation is a group of items from a larger set in a specific, linear order. …

The permutation or shorter nPr is the number of ways in which we can choose `r (r\leq n)` different objects out of a set containing `n` different objects, where the order of the elements is important.

Returns the number of permutations of a subset of r elements from a set of n elements. nPr (n,r) = n! / (n-r)!
