~~~Initial Setup~~~
|
Repeat the move:
R+ T+3 R- |
Do the move: F+3 |
Repeat the move:
L+ T-3 L- |
... until a white tile is at the top-left. |
... to get the blank tile at the front-left |
... until another white tile is at the top-right. | |
Repeat the move:
M- F-3 M+ F+3 |
Do the move: F-1 L- F+1 L+ |
Do the move: F-3 |
Do the move: F+1 R- F-1 R+ |
... until the last white tile is at the front-middle. |
Now two white tiles are on the bottom row. |
... to get the blank tile at the front-right |
Now all three white tiles are on the front row. |
The left ear can be at any of the 3 squares on the front row, so we have 3 cases to work from. Setup: Make sure that the blank tile is at the front-right (by doing an F-3 move). |
Case #1:The left ear is already located at the leftmost front tile, so you can continue onto part C: Solve the Right White Ear. | ||
Case #2:The left ear is at the middle of the front row. |
Do the move: R+ T+3 R- |
Do the move: L- F-1 L+ F+1 |
Do the move: T-2 R+ T-1 R- |
...to get all white tiles at the swapping position. |
...to get the left ear at the starting position. |
Result: all 3 white tiles are at the front, while the left ear is where it's suppose to be. | |
Case #3:The left ear is at the rightmost tile of the front row. |
Do the move: R+ T+3 R- |
Do the move: T-1 L+ T+1 L- |
Do the move: T-2 R+ T-1 R- |
...to get all white tiles at the swapping position. |
...to get the left ear at the starting position. |
Result: all 3 white tiles are at the front, while the left ear is where it's suppose to be. |
The left ear is at the leftmost tile of the front side. Setup: | |||
Do the move: F+3 L+ T-3 L- |
Do the move: R- F+1 R+ F-1 |
Do the move: T+2 L+ T+1 L- |
Do the move: T+1 R+ T-1 R- |
...to get the last green tile |
