Permutation order and sign do not determine conjugacy
ID: permutation-order-and-sign-do-not-determine-conjugacy
Conjugation preserves order of a group element, because , and preserves the sign of a permutation, because sign is a group homomorphism into . These invariants do not determine cycle type. In , and both have order three and positive sign, but have three and zero fixed points respectively. Conjugation relabels cycles, so these permutations are not conjugate.
