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 28 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
ABC4D_oP28_62_c_a_2cd_c-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oP28, then the space-group number 62, then the Wyckoff letters occupied by each element in turn (Mn: 4a; Ag: 4c; O: 4c; O: 4c; V: 4c; O: 8d). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
