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 20 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
AB6C2D_mP20_14_a_3e_e_b-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP20, then the space-group number 14, then the Wyckoff letters occupied by each element in turn (Mn: 2a; Te: 2b; O: 4e; O: 4e; O: 4e; Sr: 4e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
