^{†}The symbols for Bravais types of lattices were adopted by the International Union of Crystallography in 1985; cf. de Wolff et al. (1985).
^{‡}These conventions refer to the cells obtained by the transformations of Table 3.1.3.1. They have been chosen for convenience in this table. ^{§}. ^{¶}. ^{††}Setting with unique axis b; ; for both P and I cells, or for C cells. ^{‡‡}This number specifies the centred net among the three orthogonal nets parallel to the twofold axis and passing through (1) the shortest, (2) the second shortest, and (3) the third shortest lattice vector perpendicular to the axis. For example, `2, 3' means that either net (2) or net (3) is the centred one.
