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 152 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
AB10C4D4_mP152_14_2e_20e_8e_8e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP152, then the space-group number 14, then the Wyckoff letters occupied by each element in turn (Ag: 4e; Ag: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; C: 4e; H: 4e; H: 4e; H: 4e; H: 4e; H: 4e; H: 4e; H: 4e; H: 4e; N: 4e; N: 4e; N: 4e; N: 4e; N: 4e; N: 4e; N: 4e; N: 4e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
Note: Ag(tcm)(phz)_{1/2}.
