The Cube (game show) columns. Other equipment in the board game are track pieces, discs, clips, z shaped platform pieces, cannons, blocks, a ball flipper, a beam and card pieces,and a 7 cm x 7 cm x 7 cm plastic cube for playing a series of physical games. The cube is used for a container and to connect onto the cube platform for the electronic games. A reducer also comes with the cube, allowing it to reduce the size of the open top of the cube. This is, in almost all games involving the cube, removed in a simplify. Many well known and classic
Hilbert cube "e" > 0 must go outside the cube in some dimension. Every subset of the Hilbert cube inherits from the Hilbert cube the properties of being both metrizable (and therefore T4) and second countable. It is more interesting that the converse also holds: Every second countable T4 space is homeomorphic to a subset of the Hilbert cube. Every G-subset of the Hilbert cube is a Polish space, a topological space homeomorphic to a separable and complete metric space. Conversely, every Polish space is homeomorphic to a G-subset of the Hilbert cube. Hilbert cube In mathematics, the Hilbert cube, named after
