From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  permutation
       
           1. An ordering of a certain number of elements
          of a given set.
       
          For instance, the permutations of (1,2,3) are (1,2,3) (2,3,1)
          (3,1,2) (3,2,1) (1,3,2) (2,1,3).
       
          Permutations form one of the canonical examples of a "{group}"
          - they can be composed and you can find an inverse permutation
          that reverses the action of any given permutation.
       
          The number of permutations of r things taken from a set of n
          is
       
          	n P r = n! / (n-r)!
       
          where "n P r" is usually written with n and r as subscripts
          and n! is the {factorial} of n.
       
          What the football pools call a "permutation" is not a
          permutation but a {combination} - the order does not matter.
       
          2. A {bijection} for which the {domain} and {range} are the
          same set and so
       
          f(f'(x)) = f'(f(x)) = x.

From Bouvier's Law Dictionary, Revised 6th Ed (1856) [bouvier]:

  PERMUTATION, civil law. Exchange; barter. 
       2. This contract is formed by the consent of the parties, but delivery 
  is indispensable; for, without it, it mere agreement. Dig. 31, 77, 4; Code, 
  4, 64, 3. 
       3. Permutation differs from sale in this, that in the former a delivery 
  of the articles sold must be made, while in the latter it is unnecessary. It 
  agrees with the contract of sale, however, in the following particulars: 1. 
  That he to whom the delivery is made acquires the right or faculty of 
  prescribing. Dig. 41, 3, 4, 17. 2. That the contracting parties are bound to 
  guaranty to each other the title of the things delivered. Code, 4, 64, 1. 3. 
  That they are bound to take back the things delivered, when they have latent 
  defects which they have concealed. Dig. 21, 1, 63. See Aso & Man. Inst. B. 
  2, t. 16, c. 1; Nutation; Transfer.
