V-Cube 6 to the internal mechanism, thus making the puzzle more durable. The V-Cube 6b, which has the same "pillowed" shape as the V-Cube 7, was introduced later. There are 8 corners, 48 edges and 96 centers. Any permutation of the corners is possible, including odd permutations. Seven of the corners can be independently rotated, and the orientation of the eighth depends on the other seven, giving 8!×3 combinations. There are 96 centers, consisting of four sets of 24 pieces each. Within each set there are four centers of each color. Centers from one set cannot be exchanged with those from another
Yoshimoto Cube Yoshimoto Cube The Yoshimoto Cube is a polyhedral mechanical puzzle toy invented in 1971 by , who discovered that two stellated rhombic dodecahedra could be pieced together into a cube when he was finding different ways he could split a cube equally in half. Yoshimoto first introduced his cube in 1972 at a solo exhibition entitled "From Cube to Space," and later developed three commercial versions. In 1982, Yoshimoto Cube No. 1 was included in the Museum of Modern Art's permanent collection. The cube is made up of eight interconnected cubes which can be folded or unfolded indefinitely. The unfolded
