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
Nine-Colour Cube the puzzle and called it the Kokonotsu Pillow. Just like a regular Rubik's Cube, the Nine-Colour Cube consists of 6 face centre pieces, 12 edge pieces and 8 corner pieces; each twist rotates one face centre piece and moves the four edge and four corner pieces that surround it. However, the difference between the two puzzles is their purpose: on a standard Rubik's Cube, the aim is to arrange the puzzle in such a way that every face has only "one colour"; on the Nine-Colour Cube, the goal is opposite: to arrange it so that every face contains "all nine
