What Is Permutation with Example?

A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For example, suppose we have a set of three letters: A, B, and C. We might ask how many ways we can arrange 2 letters from that set. Each possible arrangement would be an example of a permutation.

What is called permutation?

A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.

What are the types of permutation?

Permutation can be classified into the following different types:
  • Permutation where repetition is not allowed.
  • Permutation where repetition is allowed.
  • Permutation of objects that are non-distinct.
