Abstract

A subgroup $H$ of a finite group $G$ is said to be $S$-embedded in $G$ if $G$ has a normal subgroup $T$ such that $HT$ is $S$-permutable in $G$ and ${H \cap T \leq H_{sG }}$‎. ‎$H$ is said to be $S$-semiembedded in $G$ if there is an $S$-permutable subgroup $T$ of $G$ such that $HT$ is $S$-permutable in $G$ and $H \cap T \leq H_{\overline{s}G}$; where $H_{\overline{s}G}$ is an $S$-semipermutable subgroups of $G$ contained in $H$‎. ‎In this paper‎, ‎we present some new characterization of supersolubility and nilpotency of finite groups under $S$-semiembedding property.
