Diagrams and data for the rod groups are presented. The diagrams show the symmetry elements and the general position. The data include: the origin; the asymmetric unit; the symmetry operations; the generators selected; the positions, with multiplicities, site symmetries, coordinates and reflection conditions; the symmetry of special projections; the maximal non-isotypic non-enantiomorphic subgroups; the maximal isotypic subgroups and enantiomorphic subgroups of lowest index; and the minimal non-isotypic non-enantiomorphic supergroups.
