When the mutual ratios of the three periodicities in this sandwich geometry are chosen to be the golden mean \\phi=(1+\\sqrt 5)/2, this system is believed to be statically pinned for any choice of system parameters. In the present study we overcome this pinning and force the two \"substrates\" to slide with a mutual velocity V_ext, analyzing the resulting frictional dynamics.
