Zumbo ENG 2x2 is a notation for Rubik's Pocket Cube. The notation is based on the English language. It supports 90° and 180° twists of the faces of the cube. The whole cube can be rotated along its face axes.
Clockwise 90° twists of the six faces are denoted by the tokens: «R1», «U1», «F1», «L1», «D1» and «B1», (right, up, front, left, down, back).
180° twists are denoted by appending the the tokens: «R2», «U2», «F2», «L2», «D2» and «B2».
Counterclockwise 90° twists are denoted by the tokens: «R3», «U3», «F3», «L3», «D3» and «B3».
Rotations of the whole cube along the three face axes are denoted by the capital letter «C» followed by a face twist, for example: «CR1», «CU2», «CF3».
