If k is even, or if k is odd and k 6= 2m − 1 for some m ≥ 2, then C ⊥ ⊆ C . The identity permutation is an even permutation. An even permutation can be obtained as the composition of an even number and only an even number of exchanges (called transpositions) of two elements, while an odd permutation can be obtained by (only) an odd number of transpositions. The following rules follow directly from the corresponding rules about addition of integers: WebOdd permutation is a set of permutations obtained from odd number of two element swaps in a set.

WebThe Parity Theorem says that whenever an even (resp. odd) permutation is ex-pressed as a composition of transpositions, the number of transpositions must be even (resp. odd). The purpose of this article is to give a simple deﬁnition of when a permutation is even or odd, and develop just enough background to prove the par-ity theorem.
