Decoration of two adjacent acute rhombohedra with edge length of τ2a by pM and mB clusters. (a), (b) The case where one of the two acute rhombohedra contains a pM cluster. (c) The case where acute rhombohedra contain no pM cluster. (d) The case where each acute rhombohedron includes a pM cluster. (Left) Cluster centre positions. The blue and red balls represent the centres of the pM and mB clusters, respectively. (Right) Arrangement of the pM and mB clusters. Only the cluster shells on the unit are drawn for clarity. |
