Semipermutable subgroup

In mathematics, in algebra, in the realm of group theory, a subgroup of a finite group is said to be semipermutable if commutes with every subgroup whose order is relatively prime to that of .

Clearly, every permutable subgroup of a finite group is semipermutable. The converse, however, is not necessarily true.
