Interpenetrating networks of three-dimensional Penrose tiles in CaAu3Ga, the structurally simplest cubic approximant of an icosahedral quasicrystal.
Double-Friauf polyhedra (DFPs) which play important roles in quasicrystal (QC) models are the unique building blocks in the novel 1/0 AC, CaAu(3+Delta)Ga(1-Delta) (Delta approximately equal to 0-0.13) [Pa_3; a = 9.0875(3)-9.1107(5) A]. The packing of DFPs generates interpenetrating networks of condensed three-dimensional Penrose tiles, the geometry of which is close to that assumed for QCs.
