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 34 atoms drawn above are these sites multiplied by all 4 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

A13B2C2_oP34_32_a6c_c_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oP34, then the space-group number 32, then the Wyckoff letters occupied by each element in turn (O: 2a; O: 4c; O: 4c; O: 4c; O: 4c; O: 4c; O: 4c; Re: 4c; S: 4c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
