~~~Initial Setup~~~

• All 4 red tiles are visible on the front and top rows.
• The blank tile is at the front-right.

Repeat the move:
(4 times max.)

R+ T+3 R-
L- F-3 L+

Do the move:

F+3

Repeat the move:
(4 times max.)

L+ T-3 L-
R- F+3 R+

... until a non-red tile is at the top-left.

... to get the blank tile at the front-left

... until another non-red tile is at the top-right.

Repeat the move:
(4 times max.)

M- F-3 M+ F+3

Do the move:

F-1 L- F+1 L+
T-1 L+ T+1 L-

Do the move:

F-3

Do the move:

F+1 R- F-1 R+
T+1 R+ T-1 R-

... until the last non-red tile is at the front-middle.

Now three red tiles are on the top row.

... to get the blank tile at the front-right

Now all four red tiles are on the top row.

The left ear can be at any of the 4 squares on the top row, so we have 4 cases to work from.

Setup: Make sure that the blank tile is at the front-left (by doing an F+3 move).

Case #1:

The left ear is already located at the leftmost top tile, so you can continue onto part C: Solve the Right Red Ear.

Case #2:

The left ear is at the 2nd tile of the top row.

Do the move:

L+ T-3 L-
R- F+3 R+

Do the move:

L+ T-1 L- T+1
L- F-1 L+ F+1

Do the move:

F-2 R- F-1 R+
T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

Case #3:

The left ear is at the 3rd tile of the top row.

Do the move:

L+ T-3 L-
R- F+3 R+

Do the move:

F-1 L- F+1 L+
T-1 L+ T+1 L-

Do the move:

F-2 R- F-1 R+
T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

Case #4:

The left ear is at the rightmost tile of the top row.

Do the move:

L+ T-3 L-
R- F+3 R+
L+ T-3 L-
R- F+3 R+

Do the move:

F-1 L- F+1 L+
T-1 L+ T+1 L-

Do the move:

F-2 R- F-1 R+
T+2 L+ T+1 L-
F-2 R- F-1 R+
T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

The left ear is at the leftmost tile of the top side.
Now we have to get the right ear at the rightmost tile of the top side.

Setup: Make sure that the blank tile is at the front-right (by doing an F-3 move).

Do the move:

R+ T+3 R-
L- F-3 L+

Repeat the move:
(2 times max.)

F+1 R- F-1 R+
T+1 R+ T-1 R-

Do the move:

F+2 L- F+1 L+
T-2 R+ T-1 R-

... until you have double red links on the top row

Result: All of the red links are solved.
