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 30 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

AB3C_hP30_150_ef_3g_c2d-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP30, then the space-group number 150, then the Wyckoff letters occupied by each element in turn (S: 2c; S: 2d; S: 2d; K: 3e; K: 3f; O: 6g; O: 6g; O: 6g). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
