Figure 13.4.4.1
Stereographic projections showing alternative definitions of the `standard orientation' of an icosahedron in the h-cell. Icosahedral axes are placed parallel to the cell axes. Limits of a noncrystallographic asymmetric unit are shaded, representing 1/60th of the volume of an object with icosahedral symmetry. [Reproduced with permission from Rossmann et al. (1992).] |
