Abstract:Some time ago we developed a five dimensional SO(5) superrotor model [1] which describes the energy term diagram of the lowest energy states of CH$_5^+$ surprisingly well [2]. The basis for this model lies in the S$_5$ permutation symmetry of the five identical protons in this molecule. In this contribution we discuss possible sub-group structures, in particular the embedded S$_4$$\otimes$S$_2$ $\subseteq$ S$_5$ $\subset$ SO(5), which potentially simplifies the current model and more importantly can be associated with the internal motions (vibration/rotation/internal-rotation) of the molecule. As a result the ad-hoc SO(5) model motivated by the simple super-rotor energies can be replaced by a model justified by the underlying physics. \newline\newline [1] H. Schmiedt, P. Jensen, S.
