Abstract

Diagrams and data for the two-dimensional plane 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 maximal non-isomorphic subgroups; the maximal isomorphic subgroups of lowest index; and the minimal non-isomorphic supergroups.
