- There is a standard way to do this, but not a generic method/class for it IIRC. You can do this by implementing an _act_on_() method on a wrapper class. Yet, this requires some manual input. - For cyclic actions, there is the DiscreteDynamicalSystem class introduced in https://trac.sagemath.org/ticket/24128. - There is also the Representation class in modules/with_basis/representation.py if you want to want to extend the action on the set to the module with a basis given by that set. Likely we will want to implement a class SetWithAction that automates a collects the orbit_decomposition functions and similar together as methods as a single global entry point.
