Related Polyhedra
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).

“So-called “austerity,” the stoic injunction, is the path towards universal destruction. It is the old, the fatal, competitive path. “Pull in your belt” is a slogan closely related to “gird up your loins,” or the guns-butter metaphor.”
—Wyndham Lewis (1882–1957)
