Decagonal duotegmatic alterprism

The decagonal duotegmatic alterprism is a convex isogonal polyteron that consists of 2 decagonal duotegums and 200 isosceles triangular-triangular duotegums. 2 decagonal duotegums and 30 triangular-triangular duotegums join at each vertex. It can be formed as an alterprism of a decagonal duotegum, or as the hull of two dually oriented decagonal disphenoids.
