All possible scrambles of the 1x2x3 Rubik's cube. There are 48 permutations, and we can demonstrate how.
Consider just the top face of the puzzle. With only 180° turns, we can move the top, left, right, or bottom parts. To preserve orientation, let's say top and bottom moves are identical. This means the lower middle cubie will be in a fixed position.
For the 5 cubies from the top face, there are only 12 possible orientations. For the red/orange side, since one of them is in a fixed position, we get only 4 possibilities. Red/Red/Red, Red/Red/Orange, Orange/Red/Red, Orange/Red/Orange.
For certain arrangements, the pattern is different and it depends on the green/blue side. Orientation of the puzzle is disregarded, so all of these patterns are unique.
These are the steps to go from solved to your scramble. You can determine that the maximum steps required is 6. U = up, L = left, R = right, lr = left-right (or right-left).
Individual steps are inverses of each other. Read the steps backwards to go back to solved (example: UL requires the moves LU to solve).
