An invertibility symbol is established for the C*-algebra of functional operators on the space L2(\T) generated by the multiplication operators by piecewise slowly oscillating functions and by a group of unitary operators associated to an amenable discrete group G of orientation-preserving homeomorphisms of the unit circle \T such that all g ∈ G\{e} have piecewise continuous derivatives, the same nonempty set L of periodic points, and there is a point t ∈ L with finite G-orbit.
