A subgroup A of a group G is said to be hereditarily G-permutable with a subgroup B of G, if AB(x) = B(x)A for some element x is an element of < A,B >. A subgroup A of a group G is said to be hereditarily G-permutable in G if A is hereditarily G-permutable with every subgroup of G. In this paper, we investigate the structure of a finite group G with all its Schmidt subgroups hereditarily G-permutable.
