Truncated octahedron

A truncated octahedron is an Archimedean solid. It has 14 faces: 8 are hexagons, 6 are squares. It is obtained by cutting the edges of an octahedron. Each corner of the octahedron has four connections. Cutting the corner will therefore replace it with a square.

A truncated octahedron, made of hexagons and squares.

Constructing a truncated octahedron is done by cutting the parts in red, which are pyramids, and replacing them with squares.
