2.1.3.6.7. Cubic space groups

| top | pdf |

For each cubic space group, one projection of the symmetry elements along [001] is given, Fig. 2.1.3.10[link]; for details of the diagrams, see Section 2.1.2[link] and Buerger (1956)[link]. For face-centred lattices F, only a quarter of the unit cell is shown; this is sufficient since the projected arrangement of the symmetry elements is translation-equivalent in the four quarters of an F cell. It is important to note that symmetry axes inclined to the projection plane are indicated where they intersect the plane of projection. Symmetry planes inclined to the projection plane that occur in classes [\bar{4}3m] and [m\bar{3}m] are shown as `inserts' around the high-symmetry points, such as [0,0,0]; [\textstyle{{1}\over{2}},0,0]; etc.

Cubic space groups. [\hbox{\sf G}] = general-position diagram, in which the equivalent positions are shown as the vertices of polyhedra.

The cubic diagrams given in IT (1935)[link] are different from the ones used here. No drawings for cubic space groups were provided in IT (1952)[link].
