The hexagonal bifrustum or truncated hexagonal bipyramid is the fourth in an infinite series of bifrustum polyhedra. It has 12 trapezoid and 2 hexagonal faces. This polyhedron can be constructed by taking a hexagonal dipyramid and truncating the polar axis vertices, making it into two end-to-end frustums.
Several types of crystal take this shape. [1] It has also been used in the design of 14-sided dice, which may be used to generate randomly chosen playing cards. [2]
