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 15 atoms drawn above are these sites multiplied by all 16 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

A3B11C_tP15_123_ag_ch2i_b-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol tP15, then the space-group number 123, then the Wyckoff letters occupied by each element in turn (Ce: 1a; Pd: 1b; In: 1c; Ce: 2g; In: 2h; In: 4i; In: 4i). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
