Editing Rubik's Cube (section)

===Unitary representation===
The Rubik's group can be endowed with a [[unitary representation]]: such a description allows the Rubik's Cube to be mapped into a quantum system of few particles, where the rotations of its faces are implemented by unitary operators. The rotations of the faces act as generators of the [[Lie group]].<ref>{{cite journal |author1=S. Corli |author2=L. Moro |author3=D.E. Galli |author4=E.
