Elongated pentagonal gyrobirotunda

The elongated pentagonal gyrobirotunda, or epgybro, is one of the 92 Johnson solids (J43). It consists of 10+10 triangles, 5+5 squares, and 2+10 pentagons. It can be constructed by inserting a decagonal prism between the two halves of the icosidodecahedron, seen as a pentagonal gyrobirotunda.

Vertex coordinates
