Gyroelongated pentagonal cupola
In geometry, the gyroelongated pentagonal cupola is one of the Johnson solids ("J"). As the name suggests, it can be constructed by gyroelongating a pentagonal cupola ("J") by attaching a decagonal antiprism to its base. It can also be seen as a gyroelongated pentagonal bicupola ("J") with one pentagonal cupola removed. Dual polyhedron. The dual of the gyroelongated pentagonal cupola has 25 faces: 10 kites, 5 rhombi, and 10 pentagons.
