Cube Notation

For a better and more in depth explanation about the cube moves notation visit https://ruwix.com/the-rubiks-cube/notation/

The configuration string of the cube corresponds to the color of the stickers according to the following figure

               ----------------
               | 0  | 1  | 2  |
               ----------------
               | 3  | 4  | 5  |
               ----------------
               | 6  | 7  | 8  |
               ----------------
-------------------------------------------------------------
| 9  | 10 | 11 | 18 | 19 | 20 | 27 | 28 | 29 | 36 | 37 | 38 |
-------------------------------------------------------------
| 12 | 13 | 14 | 21 | 22 | 23 | 30 | 31 | 32 | 39 | 40 | 41 |
-------------------------------------------------------------
| 15 | 16 | 17 | 24 | 25 | 26 | 33 | 34 | 35 | 42 | 43 | 44 |
-------------------------------------------------------------
               ----------------
               | 45 | 46 | 47 |
               ----------------
               | 48 | 49 | 50 |
               ----------------
               | 51 | 52 | 53 |
               ----------------

So, the color at position 0, corresponds to the color of the sticker BLU, the color at 1 is BU and so on ...

Colors used in the implementation are:

• [O]range
• [B]lue
• [R]ed
• [W]hite
• [Y]ellow
• [G]reen

NOTE

Kociemba solver needs the following cubies at place:

• 4 (Upper center): YELLOW
• 13 (Left center): BLUE
• 22 (Front center): RED
• 31 (Right center): GREEN
• 40 (Back center): ORANGE
• 49 (Down center): WHITE

TODO

• Improve documentation
• Improve Kociemba Solver tests
