General-position and symmetry-operations blocks for the space group [P2_1/c], No. 14 (unique axis b, cell choice 1). The coordinate triplets of the general position, numbered from (1) to (4), correspond to the four coset representatives of the decomposition of [P2_1/c] with respect to its translation subgroup, cf. Table[link]. The entries of the symmetry-operations block numbered from (1) to (4) describe geometrically the symmetry operations represented by the four coordinate triplets of the general-position block.
