Finite Groups all of Whose Second Maximal Subgroups are QTI-Subgroups.

A subgroup H of a finite group G is called a QTI-subgroup if C G (x) ≤ N G (H) for any 1 ≠ x ∈ H. In this article, the finite groups all of whose second maximal subgroup are QTI-subgroups are classified. [ABSTRACT FROM PUBLISHER]
