Rubik's Cube could be coloured in such a way as to emphasise the corners or edges, rather than the faces as the standard colouring does; but neither of these alternative colourings has ever become popular. The original (3×3×3) Rubik's Cube has eight corners and twelve edges. There are 8! (40,320) ways to arrange the corner cubes. Each corner has three possible orientations, although only seven (of eight) can be oriented independently; the orientation of the eighth (final) corner depends on the preceding seven, giving 3 (2,187) possibilities. There are 12!/2 (239,500,800) ways to arrange the edges, restricted from 12! because edges must
Gear Cube between. - Place those two edges on the top side and complete the following algorithm: (U2 R4) 2. Step 2: Repeat the previous step until all edge pieces are in the correct position (edge colors match the colors of the sides it is between). Phase 3: Orient the edges: (second algorithm used) Step 1: Rotate all sides until the cube is back in a cubic state using the following algorithm: R4 (repeat as necessary). There are multiple variations of the Gear Cube, ranging from the most simple, a 2x2 Gear Shift, to the most complicated, the 3x3 Even Less Gears
