This is a dual polytope of hypercube. In particular, the tesseract is the only hypercube with this property. Distributed memory machines may have hypercube or mesh interconnection schemes. Szymanski's conjecture concerns the suitability of a hypercube as a network topology for communications. This unit hypercube is the cellular automaton rule space. The number of vertices of an -dimensional hypercube is . The edge isoperimetric inequality of the hypercube is formula 76. When using Boolean weights, any document lies in a vertex in a n-dimensional hypercube. The following are the isoperimetric inequalities for the Boolean hypercube. It also has far fewer symmetries than the 24-dimensional hypercube and simplex. Equivalently, the "n"-torus is obtained from the "n"-dimensional hypercube by gluing the opposite faces together. Like the hypercube algorithm, it assumes a special communication structure. Wright visualized a genotype space as a hypercube. The 1-skeleton of a hypercube is a hypercube graph. It is a special case of the hypercube graph.
