Small disprismatopentapentachoron

The small disprismatopentapentachoron is a convex semi-uniform polychoron that is a variant of the small prismatodecachoron with only regular pentachoric and not doubled pentachoric symmetry. As such it can be represented by x3o3o3y, and has 10 tetrahedra (of two types, sizes x and y) and 20 triangular prisms (two types, forms x y3o and y x3o) as cells, with two edge lengths.
