^{†}Glide planes d with orientations (100), (010) and (001) occur only in orthorhombic and cubic F space groups. Combination of the integral reflection condition (hkl: all odd or all even) with the zonal conditions for the d glide planes leads to the further conditions given between parentheses.
^{‡}For rhombohedral space groups described with `rhombohedral axes', the three reflection conditions imply interleaving of c and n glides, a and n glides, and b and n glides, respectively. In the Hermann–Mauguin spacegroup symbols, c is always used, as in R3c (161) and , because c glides also occur in the hexagonal description of these space groups. ^{§}For tetragonal P space groups, the two reflection conditions (hhl and with ) imply interleaving of c and n glides. In the Hermann–Mauguin spacegroup symbols, c is always used, irrespective of which glide planes contain the origin: cf. P4cc (103), and . ^{¶}For cubic space groups, the three reflection conditions imply interleaving of c and n glides, a and n glides, and b and n glides, respectively. In the Hermann–Mauguin spacegroup symbols, either c or n is used, depending upon which glide plane contains the origin, cf. , , versus , , .
