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 44 atoms drawn above are these sites multiplied by all 12 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

A2B13C6D_hP44_182_bc_a2i_i_d-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP44, then the space-group number 182, then the Wyckoff letters occupied by each element in turn (Na: 2a; Co: 2b; Co: 2c; Te: 2d; Na: 12i; Na: 12i; O: 12i). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
