Figure 3
A depiction of how a set of the symmetric circle symbols generated from the objects used in International Tables, Vol. A, Table 3.2.3.1, for point-group symmetry can give rise to multiple, equally correct, interpretations of the absent symmetry operation when translated to three dimensions as compared to the 3D models with full asymmetric objects. By using the asymmetric hand object, ambiguity is removed and the three different symmetry operations implied by the spheres now give rise to unique diagrams (bottom). |
