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 9 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

A6BC2_hP9_162_k_a_d-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP9, then the space-group number 162, then the Wyckoff letters occupied by each element in turn (Pb: 1a; Sb: 2d; O: 6k). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
