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.
