Figure 14
Six 3D holohedral RBS point groups for periodic RBS crystals. The sphere from Fig. 13[link](c) for the case of v = u is shown in each panel, with appropriately placed events (blue ovals) on each hemisphere to break specific symmetries and retain others. The blue arrows associated with the events in panel (b) suggest a series of additional events stretching in the direction of the arrows. The generating symmetry elements for each group are indicated.
