Hexagonal bifrustum
Polyhedron with 14 faces / From Wikipedia, the free encyclopedia
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]
