A triakis octahedron is a three-dimensional polyhedron created from the dual of the truncated cube. This makes it a birectified truncated cube and a birectified bitruncated octahedron. Because of this, it shares the same octahedral symmetry group (Oh) as the cube the octahedron and the truncated cube. It can also be constructed by putting short triangular pyramids onto the faces of an octahedron. The Bowers acronym for a triakis octahedron is Du Tic.
