Digonal double antitegmoid

The digonal double antitegmoid, also known as domed 16, is a convex isochoric polychoron and member of the double trapezohedroid family with 16 order-6 truncated digonal-hexagonal gyronotches as cells. It is the first in an infinite family of isochoric digonal antiprismatic swirlchora.

Each cell of this polychoron has digonal symmetry, with a rectangular-symmetric hexagon, 4 mirror-symmetric pentagons, and 4 kites for faces.
