1. A generalization to Sylow permutability of pronormal subgroups of finite groups.

Author

Esteban-Romero, R., Longobardi, P., and Maj, M.

Subjects
*FINITE groups, *GENERALIZATION, *MULTIPLY transitive groups
Abstract

In this note, we present a new subgroup embedding property that can be considered as an analogue of pronormality in the scope of permutability and Sylow permutability in finite groups. We prove that finite PST-groups, or groups in which Sylow permutability is a transitive relation, can be characterized in terms of this property, in a similar way as T-groups, or groups in which normality is transitive, can be characterized in terms of pronormality.

6. On a Class of p-Soluble Groups.

Author

Ballester-Bolinches, A., Esteban-Romero, R., and Pedraza-Aguilera, M. C.

Subjects
*GROUP theory, *ISOMORPHISM (Mathematics), *ALGEBRA, *CATEGORIES (Mathematics), *SET theory, *MATHEMATICAL analysis
Abstract

Let p be a prime. The class of all p-soluble groups G such that every p-chief factor of G is cyclic and all p-chief factors of G are G-isomorphic is studied in this paper. Some results on T-, PT-, and PST-groups are also obtained. [ABSTRACT FROM AUTHOR]
