| Abstract: | In this paper,three representations of the sign of a permutation are given.The relationship between permutations and their signs are discussed.We will use the inverse ordinal number of arrangements and the number of permutation to describe the sign of permutation.By using this method,we will define the sign of permutation through cyclic structure,and some examples are given. |
