Cyclic normal Sylow subgroup for least prime divisor is central
This page describes additional conditions under which a subgroup property implication can be reversed, viz a weaker subgroup property, namely Central subgroup (?), can be made to imply a stronger subgroup property, namely normal subgroup

Suppose is the least prime divisor of the order of a finite group . Suppose is a -Sylow subgroup that is also a cyclic normal subgroup. In other words, is a normal Sylow subgroup that is cyclic as a group. Then, is a central subgroup of .
