Abstract Suppose that G is a nite p-group. If G is not a Dedekind group, then G has a non-normal subgroup. We use and to denote the maximum and minimum of the orders of the non-normal subgroups of G; respectively. In this paper, we classify groups G such that : As a by-product, we also classify p-groups whose orders of non-normal subgroups are and :
