Morphology

permutation = permute (transparent) = permute + ation

The mathematical sense (ways of arranging or ordering) directly follows from 'permute' meaning 'to arrange/change order'.

Etymology

The word permutation comes from the Latin parts per- 'completely' and mutare 'to change', the same 'mut' you see in mutation. In math and everyday use it became the name for each different way to change the order of items, so a 'permutation' is one possible arrangement.
