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 32 atoms drawn above are these sites multiplied by all 8 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
AB4C3_oI32_46_b_2bc_bc-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oI32, then the space-group number 46, then the Wyckoff letters occupied by each element in turn (Ag: 4b; C: 4b; C: 4b; N: 4b; C: 8c; N: 8c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
Note: 100 K.
