(geometry) A geometric figure in four or more dimensions, which is analogous to a cube in three dimensions. Specifically, the n-dimensional equivalent of a cube for any non-negative integer n.

Cube

(geometry) Such a figure in four dimensions; a tesseract.

A tesseract, also known as a four-dimensional hypercube. It is the 4-dimensional equivalent of a cube. This image supersedes Image:Hypercube.png. Created by the uploader using Inkscape by tracing the PNG.

(computing) A computer architecture in which each processor is connected to n others, by analogy with a hypercube of n dimensions.

Example for a prefix sum calculation. Upper number: tentatetive prefix sum (variable ${\displaystyle x}$). Lower number: sum over all elements in the sub cube (variable ${\displaystyle \sigma }$).
