This article gives the statement and possibly, proof, of an implication relation between two subgroup properties. That is, it states that every subgroup satisfying the first subgroup property (i.e., c-closed subgroup) must also satisfy the second subgroup property (i.e., powering-invariant subgroup)

Suppose G is a group and H is a c-closed subgroup of G, i.e., H occurs as the centralizer of some subset (and hence also of some subgroup) of G. Then, H is a powering-invariant subgroup of G: for any prime number p such that G is p-powered, H is also p-powered.
