Hypercube in the fourth dimension
A single point can be considered as a zero dimensional
cube, two points joined by a line are a one
dimensional cube, four points arranged in a square are
a two dimensional cube and eight points or nodes are an ordinary
three dimensional cube. Continuing this geometric
progression, the first hypercube has 16 nodes and is a
four dimensional shape (as above and
bearing in mind we cannot actually “see” in four dimensions)

A hypercube is a mathematical object in more than three dimensions.
Similar to the cube in that each two-dimensional surface of
the object is a square. It is a generalisation of a cube in more
than three dimensions.
