A gyroelongated pentagonal rotunda is formed by adjoining a pentagonal rotunda and a decagonal antiprism
along their matching decagonal bases.
The convex equilateral form with regular polygonal faces
is the Johnson solid 
.
It has 30 polyhedron vertices, 65 polyhedron edges, and 37 faces. The faces
consist of 30 equilateral triangles, 6 regular
pentagons, and one regular decagon
(McCooey).
