**"Permutation"**a test of competition

a combination of the affirmative and the counter plan simultaneously. If the permutation is successful then the counter plan is not competitive.

A permutation is an affirmative answer to a counterplan. Generally, a permutation is a combination of the plan and the counterplan. The goal of a permutation is to prove the counterplan is not competitive.

an involution precisely if it can be written as a product of non-overlapping transpositions

a surface transformation which reorders groups of eight-bit bytes

In music a permutation of a set is a transformation of its prime form by applying zero or more of certain operations, specifically transposition, inversion, and retrograde.

Barter; exchange.

the equivalent of excambion in heritable property; this is the exchange of one piece of moveable property for another (therefore a posh word for barter)

The act of permuting; exchange of the thing for another; mutual transference; interchange.

The arrangement of any determinate number of things, as units, objects, letters, etc., in all possible orders, one after the other; -- called also alternation. Cf. Combination, n., 4.

Any one of such possible arrangements.

a bet that includes several events at a time, giving you the chance to forecast different outcomes for each event

To perm a bet is to bet on all possible combinations of a selection of bets. For example, tin a parlay bet (see above), 3 selections are permed to give 7 bets covering all possible betting combinations of those selections.

All the possible combinations of a number of selections. In other words this amounts to the total number of ways in which you can combine your selections. For four selections, 1,2,3,4 you can combine the horses as follows: one four-times win bet (1234), four win trebles (123, 124, 134, 234), six win doubles (12, 13, 14, 23, 24, 34) and four win singles 1, 2, 3 and 4. These permutations are used in bets such as Double, Treble, Patent, Trixie, Yankee and Canadian.
