A subgroup \(A\) of a finite group \(G\) is called \(S\)-permutable in \(G\) if \(AS=SA\) for every Sylow subgroup \(S\) of \(G\). It is an old result of \textit{O. H. Kegel} [Math. Z. 78, 205--221 (1962; Zbl 0102.26802)] that the set \(S(G)\) of \(S\)-permutable subgroups of \(G\) is a sublattice of the lattice of all subnormal subgroups of \(G\). The author shows that \(S(G)\) is modular if and only if \(AB=BA\) for all \(A,B \in S(G)\). Using this result he gives a characterization of finite groups \(G\) for which \(S(G)\) is distributive.
