Given a group and a finite set with acting on the set then the character of the permutation representation is exactly the number of fixed points of under the action of on . That is the number of points of fixed by . This follows since, if we represent the map with a matrix with basis defined by the elements of we get a permutation matrix of . Now the character of this representation is defined as the trace of t… Web266 PERMUTATION GROUPS It remains to show that N contains a 3-cycle.

In mathematics, when X is a finite set with at least two elements, the permutations of X (i.e. the bijective functions from X to X) fall into two classes of equal size: the even permutations and the odd permutations. If any total ordering of X is fixed, the parity (oddness or evenness) of a permutation of X can be defined as the parity of the number of inversions for σ, i.e., of pairs of elements …
