Запись 𝐻 ⩽ 𝐺 означает, что 𝐻 является подгруппой группы 𝐺. Вэтой статье доказано, что класс всех SM-групп замкнут относительно произведения tcc- подгрупп. Здесь SM-группой называется группа, у которой каждая субнормальная подгруппа перестановочна с каждой максимальной подгруппой.</p></abstract><trans-abstract xml:lang="en"><p>A subgroup 𝐴 of a group 𝐺 is called tcc-subgroup in 𝐺, if there is a subgroup 𝑇 of 𝐺 such that 𝐺 = 𝐴𝑇 and for any 𝑋 ⩽ 𝐴 and 𝑌 ⩽ 𝑇 there exists an element 𝑢 ∈ ⟨𝑋, 𝑌 ⟩ such that 𝑋𝑌^𝑢 ≤ 𝐺. The notation 𝐻 ⩽ 𝐺 means that 𝐻 is a subgroup of a group 𝐺. In this paper we proved that the class of all SM-groups is closed under the product of tcc- subgroups. Here an SM-group is a group where each subnormal subgroup permutes with every maximal subgroup.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>факторизуемая группа</kwd><kwd>tcc-подгруппа</kwd><kwd>SM-группа.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>factorizable group</kwd><kwd>tcc-subgroup</kwd><kwd>SM-group.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства образования Республика Беларусь (ГПНИ «Конвергенция-2025», № гос. рег. 20211467).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Монахов В.
