Question

permutation They had rearranged the rooms in the house plans four or five times already, but the architect had come up with yet another permutation. ˌpərmjuˈteɪʃən

Accepted Answer

A change in the order of a set of objects; rearrangement, variation. There are six permutations of the letters A, B, and C, selected two at a time: AB, AC, BC, BA, CA, and CB. As you see, order is important in permutations. (By contrast, there are only three combinations: AB, AC, and BC.) Permutation is an important concept in mathematics, especially in the field of probability. But we can use the word more generally to mean any change produced by rearranging existing parts without introducing new ones. Some soap operas, for example, love permutations; the cast of regulars is constantly being rearranged into new pairs, and even triangles
