Script notations
Standard rotations :
U=Up,D=Down,F=Front,B=Back,L=Left,R=Right
Slice rotations :
E'=up-inner, M'=right-inner, S=front-inner
Block Rotations :
Uw=u=Up-block, Rw=r=Right-block, Fw=f=Front-block, ...
Cube rotations :
x=move the cube in F direction
y=move the cube in R direction
z=move the cube in U direction
Ex :
R M' R' y Rw R2
[R,U]=RUR'U' , [R:U]=RUR', (R2U2)3 , 2-4Rw=block(2,4)R
