Point group Ci

thingiverse

In crystallography, a crystallographic point group is a set of symmetry operations that transform rotations and reflections into each other while keeping a central point unchanged. These operations involve moving different directions and faces of the crystal to specific positions where features of the same kind are located. A triclinic cell is an example of such a point group, denoted as Ci in Schoenflies notation and −1 in Hermann-Mauguin notation. In orbifold notation, it is represented as x. Custom cells can be created using OpenSCAD files, which provide detailed information on how to design these unique structures.
