Подгруппа $A$ группы $G$ называется условно полунормальной в $G$, если в $G$ существует подгруппа $T$ такая, что $G=AT$ и $A$ $\mathrm{cc}$-перестановочна с каждой подгруппой из $T$. В настоящей работе доказана сверхразрешимость группы $G$, факторизуемой cверхразрешимыми условно полунормальными подгруппами $A$ и $B$, в следующих случаях: коммутант $G^\prime$ нильпотентен; ${(|A|,|B|)=1}$; $G$ метанильпотентна и ${(|G:A|,|G:B|)=1}$; $G$ метанильпотентна и ${(|A/A^{\mathfrak N}|,|B/B^{\mathfrak N}|)=1}$. Кроме того, установлена сверхразрешимость группы, у которой максимальные, силовские, максимальные из силовских, минимальные, 2-максимальные подгруппы являются условно полунормальными подгруппами.</p></abstract><trans-abstract xml:lang="en"><p>The subgroups $A$ and $B$ are said to be $\mathrm{cc}$-permutable, if $A$ is permutable with $B^x$ for some ${x\in \langle A,B\rangle}$. A subgroup $A$ of a finite group $G$ is called conditionally seminormal subgroup in $G$, if there exists a subgroup $T$ of $G$ such that $G=AT$ and $A$ is $\mathrm{cc}$-permutable with all subgroups of $T$. In this paper, we proved the supersolubility of a group $G = AB$, where $A$ and $B$ are supersoluble conditionally seminormal subgroups in $G$, in the following cases: the derived subgroup $G^\prime$ is nilpotent; ${(|A|,|B|)=1}$; $G$ is metanilpotent and ${(|G:A|,|G:B|)=1}$; $G$ is metanilpotent and ${(|A/A^{\frak N}|,|B/B^{\frak N}|)=1}$. Besides, we obtained the supersolubility of a group in which maximal subgroups, Sylow subgroups, maximal subgroups of every Sylow subgroup, minimal subgroups, 2‑maximal subgroups are conditionally seminormal subgroups.</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">Guo W., Shum K.
