Query: On the Derivation and Interpretation of the Poincar\'e-Maxwell Group   The Lie algebra of the Poincar\'e-Maxwell group is derived in a manner that
provides the interpretation of the equations of motion. It is clarified that
the dynamics obtained from the orbit method is exactly equivalent to the
classical description of the charged particle moving in the constant
electromagnetic field. The multiplicity of the coadjoint orbits of the group
under consideration is discussed.
