The fixity of a finite permutation group \(G\) is the maximal number of fixed points of a non-trivial element of \(G\). We analyze the structure of non-regular permutation groups \(G\) with given fixity \(f\). We show that if \(G\) is transitive and nilpotent, then it has a subgroup whose index and
