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 96 atoms drawn above are these sites multiplied by all 32 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

A2B3C_oF96_70_2e_fh_e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oF96, then the space-group number 70, then the Wyckoff letters occupied by each element in turn (Na: 16e; Na: 16e; Pt: 16e; O: 16f; O: 32h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
