A triakis octahedron is a Catalan solid, the dual of the truncated cube.
It can be seen as an octahedron with shallow trigonal pyramids added to the faces.
This convex polyhedron is topologically similar to the concave stellated octahedron. They have the same face connectivity, but the vertices are in different relative distances from the center.
A triakis octahedron is a vital element in the plot of cult author Hugh Cook's novel The Wishstone and the Wonderworkers.
