This article describes a result about finite groups where the isomorphism types of the Sylow subgroup (?)s implies certain properties of the whole group. Note that all -Sylow subgroups for a given prime are conjugate and hence are isomorphic, so the statement makes sense.

Statement

Suppose is a finite group with the property that every Sylow subgroup (?) of is cyclic, i.e., is a Cyclic Sylow subgroup (?). Then, is a Metacyclic group (?): it has a Cyclic normal subgroup (?) (in fact, a cyclic Normal Hall subgroup (?)) such that the quotient is also a cyclic group.
