In geometry, a tetrakis hexahedron (also called a disdyakis cube) is an Archimedean dual solid, or a Catalan solid. Its dual is the truncated octahedron. It can be seen as a cube with square pyramids covering each square face. Naturally occurring (crystal) formations of tetrahexahedrons are observed in copper and fluorite systems. Polyhedral dice shaped like the tetrakis hexahedron are occasionally used by gamers. A 24-cell viewed under a vertex-first perspective projection has a surface topology of a tetrakis hexahedron and the geometric proportions of the rhombic dodecahedron, with the rhombic faces divided into two triangles.
