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 12 atoms drawn above are these sites multiplied by all 6 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
A4B6C_hP11_143_ad_2d_b-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP11, then the space-group number 174, then the Wyckoff letters occupied by each element in turn (P: 1a; Sc: 1c; Rh: 3j; P: 3k; Rh: 3k). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
