Triangular duotegum

The 3-3 duopyramid is a noble duopyramid that consists of 9 tetragonal disphenoids and 6 vertices. It is the simplest possible duopyramid and is also the 6-2 step prism. The 3-3 duopyramid, along with its dual, is the first in a series of triangular dihedral swirlchora.

It shares the same vertex and edge configuration with the 5-dimensional hexateron.
