In this paper an extension of formalism of partner groups is proposed. The partner groups as an algebraic tool for description of laboratory and intrinsic variables are shortly introduced. A natural generalisation of partner groups is recognized as the Quantum Motion Algebra. This algebra is based on a group of motions G of a given quantum system. An example of the limiting case of of the state space L 2 (G,dμ(g)) is also considered. © 2019 Published under licence by IOP Publishing Ltd.
