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 64 atoms drawn above are these sites multiplied by all 24 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

A11B3C2_cI64_197_cdf_e_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cI64, then the space-group number 197, then the Wyckoff letters occupied by each element in turn (Hf: 8c; Ta: 8c; Hf: 12d; S: 12e; Hf: 24f). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
