Derivation of symbolic figures. Projections along vectors (a) a, (b) b and (c) c of the initial three-dimensional object – combination of two orthorhombic prisms (with `empty' and `filled' faces, making the β angle of Kupčík's cell) representing the structure motifs (units) around points with the local symmetry 2/m. Part (b) is displayed for completeness as it was not used in this study. |
