We investigate the high- and low-frequency magnetotransport of a square antidot lattice with a triangular basis. In the longitudinal magnetoresistance ρxx(B) we observe higher-order commensurability features which reflect skipping orbits along the straight edges of the antidots. A magnetic field asymmetry in the four-probe resistance along the y-direction allows us to test basic symmetry ...
