(a) Thick and thin rhombuses arranged in the PT. (b) The pentagonal base spanning building units of the PT. The distribution of the reference vertex of each type of rhombus for the orientations L23 and S24 is given: (d) class I and (e) class II. (c) The distribution for each rhombus is the sum of two regions, one lying on the first pentagon of the atomic surface and one on the second pentagon. The shape of the distribution can be obtained by sliding the rhombus on the surface of the pentagons, forming the atomic surface. All the vertices of the rhombus must be inside the atomic surface. The shape drawn by the reference vertex on the pentagon is the shape of the distribution. The distribution on the first (second) pentagon represents positions of the rhombus class I (II).
