Говорят, что подгруппа $A$ группы $G$ $\pi$-квазинормальна в $G$, если $A$ $1\pi$-субнормальна и модулярна в $G$. Доказано, что если группа $G$ $\pi _{0}$-разрешима и $ \pi$-квазинормальность является транзитивным отношением в $G$, где $\pi _{0}=\pi (D) $ и $D$ – $ \pi $-специальный корадикал группы $G$, то $D$ – абелева холлова подгруппа нечетного порядка в $G$.</p></abstract><trans-abstract xml:lang="en"><p>Throughout the article, all groups are finite. We say that a subgroup $A$ of $G$ is $\pi$-quasinormal in $G$, if $A$ is $1 \pi$-subnormal and modular in $G$. We prove that if the group $G$ is $\pi _{0}$-solvable, where $\pi _{0}=\pi (D) $ and $D$ is the $\pi $-special residual of $G$, and $\pi$-quasi-normality is a transitive relation in $G$, then $D$ is an abelian Hall subgroup of odd order in $G$.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chunikhin S.
