Elongated hexagonal bipyramid
|Elongated hexagonal bipyramid|
|Vertex configuration||2 of 36|
12 of 32.42
|Symmetry group||D6h, [6,2], (*226)|
|Dual polyhedron||Hexagonal bifrustum|
This polyhedron is in the family of elongated bipyramids, of which the first three can be Johnson solids: J14, J15 and J16. The hexagonal form can be constructed by all regular faces, but isn't a Johnson solid because 6 equilateral triangles would form six co-planar faces (in a regular hexagon).
- A quartz crystal is an example of an elongated hexagonal bipyramid. Because it has 18 faces, it can be called an octadecahedron. Other chemicals also have this shape.
- The edge-first orthogonal projection of a 24-cell is an elongated hexagonal bipyramid.
- Used as the shape of Fruit Gushers candy.
- Used as a physical manifestation for assisting various branches of three-dimensional graph theory.
