Christine R. Hankermeyer,Ronald S. Tjeerdema extended the CT to digraphs, by proving a similar statement..Calling . a non-trivial permutation whose orbits all have the same length, Maru“sic and Jordan have independently asked whether every VT-graph has an automorphism acting semiregularly on its vertex set, as happens for Cayley graphs.

James L. Byardproblem in theoretical chemistry. Any progress in understanding reactivity not only enriches chemical knowledge but also has important practical implications. Numerous methods have been developed to assess reactivity quantitatively, and it is not the aim of this chapter to review all of them. Yet, s
