Pocket Cube court affirmed the judgment that Rubik's 2×2×2 Pocket Cube infringed Nichols's patent, but overturned the judgment on Rubik's 3×3×3 Cube. Any permutation of the eight corners is possible (8! positions), and seven of them can be independently rotated (3 positions). There is nothing identifying the orientation of the cube in space, reducing the positions by a factor of 24. This is because all 24 possible positions and orientations of the first corner are equivalent due to the lack of fixed centers. This factor does not appear when calculating the permutations of N×N×N cubes where N is odd, since those puzzles
Gear Cube the inventor of the Pyraminx. Gear Cube The Gear Cube is a 3-D combination puzzle designed and created by Dutch puzzle maker Oskar van Deventer (based on an idea by Bram Cohen). It was initially produced by Shapeways in 2009 and known as "Caution Cube" due to the likeliness of getting fingers stuck between the gears while speedcubing. Later, in 2010, it was mass-produced by Meffert's as the "Gear Cube". Compared to the original Rubik's Cube, this cube uses a complete gear mechanism. It requires six 180° turns to complete one rotation resulting in a twisty puzzle. The design of
