hiperkubus

Also known as n-cube, n-eract, octachoron

In geometry, a hypercube is an n-dimensional analogue of a square (two-dimensional|) and a cube (Three-dimensional|); the special case for Four-dimensional space| is known as a tesseract. It is a closed, compact, convex figure whose 1-skeleton consists of groups of opposite parallel line segments aligned in each of the space's dimensions, perpendicular to each other and of the same length. A unit hypercube's longest diagonal in n dimensions is equal to \sqrt{n}.
