Transitivity of varietal hypercube networks

The varietal hypercube VQ _n is a variant of the hypercube Q _n and has better properties than Q _n with the same number of edges and vertices. This paper proves that VQ _n is vertex-transitive. This property shows that when VQ _n is used to model an interconnection network, it is high symmetrical and obviously superior to other variants of the hypercube such as the crossed cube.
