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 40 atoms drawn above are these sites multiplied by all 48 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

A3B4C3_cI40_220_a_c_b-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cI40, then the space-group number 220, then the Wyckoff letters occupied by each element in turn (Au: 12a; Y: 12b; Sb: 16c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
