Gyroelongated pentagonal cupola

The gyroelongated pentagonal cupola, or gyepcu, is one of the 92 Johnson solids (J24). It consists of 5+5+5+10 triangles, 5 squares, 1 pentagon, and 1 decagon. It can be constructed by attaching a decagonal antiprism to the decagonal base of the pentagonal cupola.

If a second cupola is attached to the other decagonal base of the antiprism, the result is the gyroelongated pentagonal bicupola.

Vertex coordinates
A gyroelongated pentagonal cupola of edge length 1 has the following vertices: where H = $$\sqrt{\frac{-4-2\sqrt5+\sqrt{50+22\sqrt{5}}}8}$$is the distance between the decagonal antiprism's center and the center of one of its bases.
