Brillouin zone with asymmetric unit and representation domain of CDML for arithmetic crystal class [m\overline{3}mI]. Space groups: [Im\overline{3}m-O_h^9] (229), [Ia\overline{3}d-O_h^{10}] (230). Reciprocal-space group ([Fm\overline{3}m])*, No. 225 (see Table 1.5.5.1[link]). The representation domain of CDML is identical with the asymmetric unit. Auxiliary points: R: [\textstyle{1 \over 2},\textstyle{1 \over 2},\textstyle{1 \over 2}]; N2: [\textstyle{1 \over 4},\textstyle{1 \over 4},\textstyle{1 \over 2}]; H2: [0,0,\textstyle{1 \over 2}]. Flagpole: [F_1=[P\,R]\quad x,x,x]: [\textstyle{1 \over 4} \,\lt \, x \,\lt \, \textstyle{1 \over 2}]. Wing: [B_1 \cup J_1=[\Gamma\,P\,N_2\,H_2]\backslash[F_3]] [ x,x,z]: [0 \,\lt \, x \,\lt \, \textstyle{1 \over 4}]; [x \,\lt \, z \,\lt \,\textstyle{1 \over 2}] with [z \neq \textstyle{1 \over 2} - x].
