Decagonal duotruncatoprism

The decagonal duotruncatoprism or dedtep is a convex isogonal polychoron and the eighth member of the duotruncatoprism family. It consists of 20 didecagonal prisms, 100 rectangular trapezoprisms, 200 wedges, and 100 tetragonal disphenoids. 2 didecagonal prisms, 2 rectangular trapezoprisms, 3 wedges, and 1 tetragonal disphenoid join at each vertex. It can be obtained as the convex hull of two orthogonal decagonal-icosagonal duoprisms whose icosagonal prisms have a smaller circumradius than their decagonal prisms. However, it cannot be made uniform.
