# Ooooh, Sexy

Geometry Level 3

When solving a Rubik's Cube, a common algorithm in speedcubing is the "sexy move," in which the solver performs the moveset $$R$$ $$U$$ $$R'$$ $$U',$$ meaning, "rotate the rightmost face $$90^{\circ}$$ clockwise, then the uppermost face $$90^{\circ}$$ clockwise, then the rightmost face $$90^{\circ}$$ counterclockwise, then the uppermost face $$90^{\circ}$$ counterclockwise."

How many times will a solver have to perform the "sexy move," starting in a solved state, before he returns to the solved state again?
