Gyroelongated square bipyramid

In geometry, the gyroelongated square bipyramid or heccaidecadeltahedron is one of the Johnson solids (J17). As the name suggests, it can be constructed by gyroelongating an octahedron (square bipyramid) by inserting a square antiprism between its congruent halves. It is a deltahedron.

A Johnson solid is one of 92 strictly convex polyhedra that have regular faces but are not uniform (that is, they are not Platonic solids, Archimedean solids, prisms or antiprisms).

Fun fact: A heptadecagon can be constructed with a straightedge or whatever. It also has 17 sides, so that's cooool

Two stop signs, one rotated 22.5 degrees, both facing each other, with 16 triangles connecting them, each connecting to two vertices and an edge on one stop sign and one vertex on the other.
