As its name implies, the shape can be truncated from the octahedron. Further truncated structures could be cuboctahedron and cubo-truncated rhombic dodecahedron. Here, the Au116 could be a middle structure between the truncated octahedron and cuboctahedron.
The structures were obtained from the literature (A. S. Barnard, Accounts of Chemical Research, 2012, 45, 1688-1697).
