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
Floppy Cube Floppy Cube The Floppy Cube is a cuboidal twisty puzzle in the style of the Rubik's Cube. It was originally invented by Katsuhiko Okamoto and mass-produced by Gentosha Toys, although several other companies have since mass-produced it as well.
