    • n permutation Interchange; concurrent changes; mutual change; change in general.
    • n permutation Exchange; barter.
    • n permutation In mathematics, a linear arrangement of objects resulting from a change of their order. Permutation differs from combination in this, that in the latter there is no reference to the order in which the quantities are combined, whereas in the former this order is considered, and consequently the number of permutations always exceeds the number of combinations.If n represents the number of quantities, then the number of permutations that can be formed out of them, taking two by two together, is n X (n-1); taken three and three together, it is n X (n-1) X (n-2); and so on. Sometimes called alternation. See combination, 5.
    • n permutation In philology, the mutation or interchange of consonants, especially of allied consonants.
