Abstract:
Let H and X be subgroups of a finite group G. Then we say that H is: X-quasipermutable (respectively, XS-quasipermutable) in G provided G has a subgroup B such that G=NG(H)B and H X-permutes with B and with all subgroups (respectively, with all Sylow subgroups) V of B such that (|H|,|V|)=1; X-propermutable (respectively, XS-propermutable) in G provided G has a subgroup B such that G=NG(H)B and H X-permutes with B and with all subgroups (respectively, with all Sylow subgroups) of B.
In this paper we analyze the influence of X-quasipermutable, XS-quasipermutable, X-propermutable and XS-propermutable subgroups on the structure of G.
Keywords:
