The disdyakis dodecahedron is the dual polyhedron of the Archimedean great rhombicuboctahedron.
It is also called the hexakis octahedron (Unkelbach 1940; Holden 1971, p. 55).
It is illustrated above together with a wireframe version and a net
that can be used for its construction.
It is Wenninger dual .
If the original great rhombicuboctahedron
has unit side lengths, then the resulting dual has edge lengths
