The multiplicity and the Wyckoff letter say how many copies of the site the group makes in one cell and on which kind of symmetry element the site sits; the 20 atoms drawn above are these sites multiplied by all 12 operations. Press Wyckoff under Colour to see the sites, and tick a symmetry element on the left to see which atoms lie on it.

How to read the label

ABC3_cP20_198_a_a_b-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP20, then the space-group number 198, then the Wyckoff letters occupied by each element in turn (Cl: 4a; Na: 4a; O: 12b). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
