Equivalently, a subgroup is paranormal if its weak closure and normal closure coincide in all intermediate subgroups. Here are some facts relating paranormality to other subgroup properties: * Every pronormal subgroup, and hence, every normal subgroup and every abnormal subgroup, is paranormal. * Every paranormal subgroup is a polynormal subgroup. * In finite solvable groups, every polynormal subgroup is paranormal.
