I'm considering the normalizer of the subgroup generated by the element $(12)(345)$. I know that this is exactly the elements of $S_5$ that commute with it and it's a subgroup of $S_5$, but not necessarily of the subgroup generated by $(12)(345)$ itself. I certainly have the identity permutation, $(12)(345)$ itself, and its inverse. However, I do not know if there are any others or an efficient algorithm to use. Is there a way to use the conjugacy class of $(12)(345)$?
