"What exactly is a 4-D cube, or tesseract? What a point is to a line, a line is to a square; what a square is to a cube, a cube is to a tesseract. Some of the tesseract's geometric properties can be worked out, for instance: a line is bounded by two points, a square by four, a cube by eight and a tesseract by sixteen. A line is held within two points, a square within four lines, a cube within six squares and a tesseract within eight cubes."
