bipyramid

The dual of a right prism is a bipyramid.

The shape of the molecule is a distorted trigonal bipyramid.

A zircon crystal is an example of an elongated square bipyramid.

Starting from a trigonal bipyramid, a face is capped.

This is the rotation group of a regular prism, or regular bipyramid.

The term dodecadeltahedron is sometimes used to distinguish the bipyramid from the Platonic solid.

An icosahedron can also be called a gyroelongated pentagonal bipyramid.

A perfect pentagonal bipyramid belongs to the molecular point group D .

Using the standard nomenclature for Johnson solids, an octahedron would be called a square bipyramid.
