RPS Code Editor

The Regular Point System code editor edits and checks RPS code. RPS codes show symmetry operators as (x, y, z) coordinates (Fig. 1).

The only RPS code necessary to define the Silicon structure is (x + 1/4, y + 1/4, z + 1/4). Indeed Si must be declared Face Centered Cubic without a center of symmetry and its lattice parameter set to 0.543 (Fig. 2).
