如果它与 G 与的每亚群 K 是可变更的,组 G 的亚群 H 被称为 semipermutable (|H| , |K|)= 1,并且 s-semipermutable 如果它与 G 与的每 Sylow p 亚群是可变更的(p, |H|)= 1。在这份报纸,为可解决的一个组的一些足够的条件以 s-semipermutability 被获得。
A subgroup H of a group G is called semipermutable if it is permutable with every subgroup K of G with (|H|, |K|) = 1, and s-semipermutable if it is permutable with every Sylow p-subgroup of G with (p, |H|) = 1. In this paper, some sufficient conditions for a group to be solvable are obtained in terms of s-semipermutability.
