Key Concepts

Permutation

A permutation is an arrangement of objects in a specific order. It is a fundamental concept in combinatorics, used to count the number of possible ordered arrangements of a subset or the entire set of objects.

Factorial Function

The factorial function, represented by n!, is the product of all positive integers from 1 to n. It is a key operation in many combinatorial formulas, particularly in calculating permutations and combinations.

Permutation Formula

The permutation formula is used to calculate the number of ways to arrange r objects from a collection of n objects. It is given by P(n, r) = n!/(n-r)!, which accounts for the order of selection in the arrangement.
