permutation permuteš, jâygašt Fr.: permutation Math.: A rearrangement of the elements of a set in a particular order. The number of permutations of n objects is equal to n! (→ factorial n). For example, there are 24 permutations of letters A, B, C, and D (4! = 1 × 2 × 3 × 4). The number of permutations of n objects taken r at a time is denoted by ^{n}P_{r} and equals n! / (n - r)!. For example, the number of permutation of A, B, C, and D taken two at a time is 12. If n objects are of k different kinds, with r_{1} alike of one kind, permutations of n objects equals n! / r_{1}! r_{2}! ... r_{k}!, where r_{1} + r_{2} + ... r_{k} = n. Verbal noun of → permute. Permuteš, verbal noun of → permute. |
