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 28 atoms drawn above are these sites multiplied by all 8 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

A2B5_mC28_15_f_e2f-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mC28, then the space-group number 15, then the Wyckoff letters occupied by each element in turn (Pd: 4e; B: 8f; Pd: 8f; Pd: 8f). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
