"A small stellated dodecahedron can be constructed by cumulation of a dodecahedron,
i.e., building twelve pentagonal pyramids and attaching them to the faces of the original dodecahedron."

"Another way to construct a great stellated dodecahedron via cumulation is to make 20 triangular pyramids [...] and attach them to the sides of an icosahedron."
