О дополняемости элементов решетки разрешимых регулярных транзитивных подгрупповых функторов

This paper investigates the properties of the lattice of all solvable regular transitive subgroup functors. We prove that this lattice is a lattice with complements. We construct an example showing that is not a lattice with unique complements. It is noted that it is not modular.
