Abstract: Let $ D$ be a normal set of involutions in a finite group. Form the involutory graph with vertex set $ D$ by joining distinct commuting elements of $ D$. Assume the product of any two such elements is in $ D$, and the graph is disconnected. Then the group generated by $ D$ contains a strongly embedded subgroup. Two corollaries are proved.
