Cube only member of that group that is a zonohedron (every face has point symmetry). The cube can be cut into six identical square pyramids. If these square pyramids are then attached to the faces of a second cube, a rhombic dodecahedron is obtained (with pairs of coplanar triangles combined into rhombic faces). The analogue of a cube in four-dimensional Euclidean space has a special name—a tesseract or hypercube. More properly, a hypercube (or "n"-dimensional cube or simply "n"-cube) is the analogue of the cube in "n"-dimensional Euclidean space and a tesseract is the order-4 hypercube. A hypercube is also called
Gleaming the Cube to the cryptic question "Have you ever gleemed [sic] inside a cube?" that Garry Scott Davis (GSD) asked Neil Blender in an interview in the December 1983 issue of "Thrasher" magazine. In the film, Christian Slater's character defines "gleaming the cube" as "pushing your limits to the edge". The DVD contains an easter egg; by highlighting the skateboard on the main menu, viewers can watch a short featurette entitled "What Does Gleaming the Cube Mean?".
