# permutations of unordered sets

## Overview

11/9/2016 permutations of an unordered set can be accomplished by taking any item of the collection of words, followed by any non-previous item of any of the previous items, repeated ad infinitum.

Example:

```word set: gh ab ef cd

by definition, the permutation would be the set itself. maybe that's why it never got out there.

I do not remember what a permutation is. my math books are gone, and I am informed I can't look it up in a dictionary (you know you can expand your brain too much guys).
and I am not a mathematition. I am a software engineer.
unordered combinations for the same set would be below, and you can simply sort the set
and try again.

permutations:
gh ab ef cd
gh ab cd ef
gh ef ab cd
gh ef cd ab
gh cd ab ef
gh cd ef ab

cd gh ab ef
cd gh ef ab
cd ab ef gh
cd ab gh ef
cd ef gh ab
cd ef ab gh

ab gh cd ef
ab gh ef cd
ab cd ef gh
ab cd gh ef
ab ef gh cd
ab ef cd gh

ef ab gh cd
ef ab cd gh
ef cd gh ab
ef cd ab gh
ef gh cd ab
ef gh ab cd
-->
4 sets of 6 permutations which make 24 total.
