WebMar 24, 2024 · The hypercube is a generalization of a 3-cube to n dimensions, also called an n-cube or measure polytope. It is a regular polytope with mutually perpendicular sides, and is therefore an … In graph theory, the hypercube graph Qn is the graph formed from the vertices and edges of an n-dimensional hypercube. For instance, the cube graph Q3 is the graph formed by the 8 vertices and 12 edges of a three-dimensional cube. Qn has 2 vertices, 2 n edges, and is a regular graph with n edges touching each vertex. The hypercube graph Qn may also be constructed by creating a vertex for each subset of an n-el…
