Superset ENG 2x2
Superset ENG 2x2 is a notation for Rubik's Cubes with 2 layers, such as the Pocket Cube. The notation is based on the English language. It supports 90° and 180° twists of the faces of the cube. A whole cube can be rotated along its face axes. Permutation and orientation changes of individual cube parts can be specified using permutation cycles.

Clockwise 90° twists of the six faces of the cube are described by the capital letters: R, U, F, L, D and B, (right, up, front, left, down, back). For example, R rotates the right face in clockwise direction as seen from the right face.
Counterclockwise twists and rotations are described by appending the inversion operator ' to a move: R', U', F', ...
In environments, where the ' character can not be used, the character - can be used as an alternative inversion operator.
180° twists and rotations are described by appending the number 2 to a move: R2, U2, F2, ...
Cube rotations: CR, CR', CR2

Rotations of the whole cube are described by prepending the letter C to a face twist. For example, CR rotates the whole cube in clockwise direction as seen from the right face.
Grouping
Sequences of moves can be grouped using brackets: (R U F).
Repetition
Moves and groups can be repeated multiple times by appending the number of repetitions to the closing bracket: (R U F)3.
