It’s a geometrical thing. Extend an *n*-dimensional object into *n*+1 dimensions:
* 0 dim: 1 point
* 1 dim: 2 points connected by 1 line
* 2 dim: 4 points connected by 4 lines forming 1 surface
* 3 dim: 8 points, 12 lines, 6 faces, forming 1 cube
* 4 dim: 16 points, 32 lines, 18 faces, 6 cubes, forming 1 hypercube
* 5 dim: …
