The hendecagonal duotegum or hendit, also known as the hendecagonal-hendecagonal duotegum, the 11 duotegum, or the 11-11 duotegum, is a noble duotegum that consists of 121 tetragonal disphenoids and 22 vertices, with 22 cells joining at each vertex. It is also the 22-10 step prism. It is the first in an infinite family of isogonal hendecagonal hosohedral swirlchora and also the first in an infinite family of isochoric hendecagonal dihedral swirlchora.
