Let G be a finite group and H a subgroup of G. Recall that H is said to be a TI-subgroup of G if Hg∩ H = 1 or H for each g ∈ G. In this note, we prove that if all non-nilpotent subgroups of a finite non-nilpotent group G are TI-subgroups, then G is soluble, and all non-nilpotent subgroups of G are normal.
