Certain colored graphs are defined in terms of permutations in S, and the edge-chromatic automorphism groups of these graphs are studied. In fact, these groups are characterized in terms of the associated permutations. These groups are related to the groups of symmetries of certain drawings of cycle
The present paper investigates the groups of automorphisms for some lattices of modal logics. The main results are the following. The lattice of normal extensions of S4.3, NExt S4:3, has exactly two automorphisms, NExt K:alt1 has continuously many automorphisms. Moreover, any automorphism of NExt S4
