In geometry, the elongated bipyramids are an infinite set of polyhedra, constructed by elongating an n-gonal bipyramid (by inserting an n-gonal prism between its congruent halves).
There are three elongated bipyramids that are Johnson solids:
Elongated triangular bipyramid (J14),
Elongated square bipyramid (J15), and
Elongated pentagonal bipyramid (J16).
Higher forms can be constructed with isosceles triangles.
