Finite groups with some generalized smooth maximal subgroups

A finite group G is called smooth group if it has a maximal chain of subgroups in which any two intervals of the same length are isomorphic (as a lattice). A group G is called totally smooth group if all its maximal chains are smooth and is called generalized smooth if the chain [G/L] is totally smooth for every subgroup L of G of prime order. Let Gp be a Sylow p-subgroup of G. In this paper, we introduce the structure of a non-simple group G if |Gp|>p and all maximal subgroups of Gwhose order is divisible by the prime p are totally smooth groups (or generalized smooth groups) and hence we conclude an unexpected result which represents the main theorem of this paper.
