An elongated pentagonal gyrocupolarotunda is formed by attaching a pentagonal cupola and a pentagonal rotunda to the
two decagonal bases of a decagonal prism, with their outer pentagonal faces rotated by 
relative to one another.

The convex equilateral form with regular polygonal faces
is the Johnson solid 
.
It has 35 polyhedron vertices, 70 polyhedron edges, and 37 faces. The faces consist of 15 equilateral triangles, 15 squares, and 7 regular pentagons (McCooey).
