Necessary conditions are given for the pronormality of a regular cyclic subgroup of a finite symmetric group. The degree of their sufficiency is discussed.doi:10.1007/BF01094383R. I. TyshkevichKluwer Academic Publishers-Plenum PublishersJournal of Soviet Mathematics...
We study free subgroups of index four of the parametrized modular group II, the subgroup of SL(2; [ξ]) generated by (1ξ0 1) and (0 -1 1 0 ). There are eight free subgroups, four of which are normal and four are non-normal. Then we study the intersections of the normal subgro...

A (p ,n) group G is a permutation group (on a set Ω) which possesses a regular normal elementary abelian subgroup of order pn. The set Ω may be identified with a vector space V on which Go, the stabilizer of a point in G, acts as a subgroup of the general linear group GL(n...
The subgroup H is called pronormal in a group G if for every g∈G the subgroups H, g -1 Hg are conjugate in the subgroup generated by them. A group G is called locally stepped if every of its finitely generated subgroups has a proper subgroup of finite index. The authors give a cha...
