Function.Commute.right_bijOn_fixedPoints_comp

∀ {α : Type u_1} {f g : α → α},
  Function.Commute f g → Set.BijOn g (Function.fixedPoints (f ∘ g)) (Function.fixedPoints (f ∘ g))

If self-maps f and g commute, then g is bijective on the set of fixed points of f ∘ g. This is a particular case of Function.bijOn_fixedPoints_comp.
