Information on Permutations ...

This page gives a brief explanation of the input and output options available on the "Generate Permutations" page. More extensive explanation is given on the following pages.

Permutations

A permutation of objects is an arrangement of those objects in some order; that is, some object is placed in the first position, another in the second position, and so on, until all objects have been placed. For our purposes, a permutation is a string a1 a2 ... an, where each ai is an element of the set [n] = {1,2,...,n} and each element occurs precisely once. For example, the permutations of [3] = {1,2,3} are 123, 132, 213, 231, 312, 321.

COS can be used to generate many restricted types of permutations.
