Hendecagonal duotegmatic alterprism

The hendecagonal duotegmatic alterprism is a convex isogonal polyteron that consists of 2 hendecagonal duotegums and 242 isosceles triangular-triangular duotegums. 2 hendecagonal duotegums and 33 triangular-triangular duotegums join at each vertex. It can be formed as an alterprism of a hendecagonal duotegum, or as the hull of two dually oriented hendecagonal disphenoids.
