A Great Stellated Dodecahedron A convex regular icosahedron is the foundation for making this great stellated dodecahedron. Stellated means "star-like". The icosahedron is transformed into a star-like polyhedron by attaching twenty isosceles triangular pyramids. A great stellated dodecahedron has 12 faces, 20 vertices and 30 edges. The convex regular dodecahedron is one of the five regular Platonic solids. The convex regular dodecahedron has three stellations, all of which are regular star…
