| Apr 13, 2016 at 6:49 | comment | added | fffred | Yes. That's why you need to put 6 pieces so that only cubes 2x2x2 remain. Another way to see this: 4x4x4 has 9 degrees of freedom (3 rotations per axis x y or z); you block 6: remain 3, just like a 2x2x2 Rubik's cube. Note that Kevin's solution starts with similar fashion as mine, but forgets to remove duplicates. | |

| Apr 13, 2016 at 6:40 | comment | added | fffred | What I mean is that one layer cannot rotate with respect to the one below as long as one piece of tape joins them. You do not need tapping the entire face. | |
