    Players take turns moving to the Essentials, Permitted Premises, or Permitted Rules sections of the mat. Any cube moved to Essentials must be used in any Solution, and must be an essential part of that solution; any cube value in Permitted Premises may be used as part of a premise; any cube value in Permitted Rules may be used as part of a Rule.

    However, Eberhard's theorem states that it should be possible to form a simple polyhedron by adding some number of hexagons, and in this case one hexagon suffices: bisecting a cube on a regular hexagon passing through six of its faces produces two copies of a simple roofless polyhedron with three triangle faces, three pentagon faces, and one ...

    The cube of a number n is denoted n 3, using a superscript 3, [a] for example 2 3 = 8. The cube operation can also be defined for any other mathematical expression, for example (x + 1) 3. The cube is also the number multiplied by its square: n 3 = n × n 2 = n × n × n. The cube function is the function x ↦ x 3 (often denoted y = x 3) that

    Magic Cube 5D by Roice Nelson is capable of rendering 5-cube puzzles in six sizes from 2 5 to 7 5. Allows 5D twists and controls for rotating the cube in multiple dimensions, 4-D and 5-D perspective controls, cubie and sticker spacing and size controls, similar to Magiccube4D. However, a 5-D puzzle is much more difficult to comprehend than a 4 ...
