In particular, median graphs are isometric subgraphs of hypercubes, and are therefore partial cubes. Isometric embeddings of graphs into hypercubes have an important application in chemical graph theory. The tesseract, like all hypercubes, tessellates Euclidean space. These are the measure polytopes or hypercubes. These agree with elementary calculations of the volumes of cross-polytopes and hypercubes. The set of polytopes formed by alternating the hypercubes are known as demicubes. It is a part of an infinite family of polytopes, called hypercubes. Polygons of the form {4} are called generalized hypercubes (squares for polygons). Wormhole techniques are primarily used in multiprocessor systems, notably hypercubes. They are also two-dimensional representations of hypercubes. Salvador Dali once sought him out to discuss four-dimensional hypercubes. Since their discovery, four-dimensional hypercubes have been a popular theme in art, architecture, and fiction. It is denoted by det and acts on all hypercubes over such a field. In case of Hypercubes the average distance is given as n/2. It is given as 2 for Hypercubes.
