(a) The rhombic triacontahedron, the elementary volume used to describe Tsai QCs and ACs. (b) The two linkage rules applying to RTHs, either by sharing a face along a 2-fold axis (b-linkage) or by intersecting and sharing an obtuse golden rhombohedron along a 3-fold axis (c-linkage). (c) Representation of the unit cell of 1/1 ACs as a network of intersecting RTHs.
