We derive the equations of motion for test particles and light rays and present their solutions in terms of the Weierstrass ℘, ζ and σ functions as well as the Kleinian σ function. With the help of parametric diagrams and effective potentials we analyze the geodesic motion and classify the possible orbit types. This spacetime is also a solution of f (R) gravity with a constant curvature scalar.
