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 gears externally in order for the mechanics to be seen. At first sight, it looks quite formidable, nevertheless it is actually simpler to solve than the original Rubik's Cube. There are two objectives when solving the cube. The first goal is taking the mixed up puzzle back to its original cubic state. The second goal is to actually solve the puzzle by arranging each side back to their own beginning colors. The Gear Cube has a design like no other because the puzzle is made almost completely out of gears. The cube has 12 edge pieces, four on every layer,
