Abstract

Let GG be a permutation group on a set Ω\Omega, and kk a positive integer. The kk-closure G(k)G^{(k)} of GG is the largest subgroup of Sym(Ω)\operatorname{Sym}(\Omega), with the same as GG orbits of componentwise action on Ωk\Omega^k. We prove that the kk-closure of a finite nilpotent permutation group is the direct product of kk-closures of its Sylow subgroups.
