Pentagonal duotruncatoprism

The pentagonal duotruncatoprism or pedtep is a convex isogonal polychoron and the fourth member of the duoexpandoprism family. It consists of 10 dipentagonal prisms, 25 rectangular trapezoprisms, 50 wedges, and 25 tetragonal disphenoids. 2 dipentagonal 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 semi-uniform pentagonal-dipentagonal duoprisms whose dipentagonal prism cells have a smaller coircumradius than the pentagonal prisms. However, it cannot be made uniform.
