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 rows and as well as 180° turns on four rows. Gear Cube Ultimate: This cube is built exactly like the Gear Cube Extreme with only eight gears. The only difference is that it added Tony Fisher style stickers to the four inner pieces on each side, making it one step more difficult to correctly orient the six sides. A common issue while solving this cube is having the entire puzzle complete except for the newly added stickers being mismatched with different sides. Even Less Gears: The only 3x3 type of Gear Cube with a total of four gears. It takes
