-A '''permutation''' of a [[set]] of <math>r</math> objects is any rearrangement (linear ordering) of the <math>r</math> objects.  There are <math>r!</math> (the [[factorial]] of <math>r</math>) permutations of a set with <math>r</math> distinct objects.
-One can also consider permutations of [[infinite]] sets.  In this case, a permutation of a set <math>S</math> is simply a [[bijection]] between <math>S</math> and... [[Permutation|[more]]]
