Abstract

Mathematics Physical Sciences Science & Technology
Let G be a finite group. We say that G is a T-0-group, if its Frattini quotient group G/Phi (G) is a T-group, where by a T-group rye mean a group in which every subnormal subgroup is normal. We determine the structure of a non T-0-group C all of whose propel subgroups are T-0-groups.
