Transposition
An exchange of two elements of an ordered list with all others staying the same. A transposition is therefore a permutation of two elements. For example, the swapping of 2 and 5 to take the list 123456 to 153426 is a transposition. The permutation symbol epsilon_(ijk...) is defined as (-1)^n, where n is the number of transpositions of pairs of elements that must be composed to build up the permutation.
