In mathematics, a permutation of a set can mean one of two different things: an arrangement of its members in a sequence or linear order , or the act or process of changing the linear order of an ordered set.

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 number of possible permutations for items in a set is often represented as …

So, in Mathematics we use more precise language: When the order doesn't matter, it is a Combination. When the order does matter it is a Permutation.
