Доказана модулярность такой решетки формаций для любого подгруппового функтора τ и всякого непустого множества простых чисел ω. В частности, получен положительный ответ на вопрос А. Н. Скибы и Л. А. Шеметкова (2000 г.) о модулярности решетки c∞ L всех тотально L-композиционных формаций. Установлено, что решетка c τ ω∞ является полной подрешеткой решетки cω ∞ всех тотально ω-композиционных формаций конечных групп.</p></abstract><trans-abstract xml:lang="en"><p>We study the properties of the lattice c τ ω∞ of all τ-closed totally ω-composition formations of finite groups. We prove the modularity of such a lattice of formations for any subgroup functor τ and any nonempty set ω of primes. In particular, we obtain a positive answer to the question of A. N. Skiba and L. A. Shemetkov (2000) about the modularity of the lattice c∞ L of all totally L-composition formations. We establish that the lattice c τ ω∞ is a complete sublattice of the lattice cω ∞ of all totally ω-composition formations of finite groups.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конечная группа</kwd><kwd>формация групп</kwd><kwd>подгрупповой функтор</kwd><kwd>композиционная формация</kwd><kwd>ω-композиционная формация</kwd><kwd>тотально композиционная формация</kwd><kwd>решетка формаций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>finite group</kwd><kwd>formation of groups</kwd><kwd>subgroup functor</kwd><kwd>composition formation</kwd><kwd>ω-composition formation</kwd><kwd>totally composition formation</kwd><kwd>lattice of formations</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Скиба, А.
