The tridecagonal duotegum or taddit, also known as the tridecagonal-tridecagonal duotegum, the 13 duotegum, or the 13-13 duotegum, is a noble duotegum that consists of 169 tetragonal disphenoids and 26 vertices, with 26 cells joining at each vertex. It is also the 26-12 step prism. It is the first in an infinite family of isogonal tridecagonal hosohedral swirlchora and also the first in an infinite family of isochoric dodecagonal dihedral swirlchora.
