en "A small stellated dodecaedru can be constructed by cumulation of a dodecaedru, i.e., building twelve pentagonal pyramids and attaching them to the faces of the original dodecaedru." Eric W. Weisstein, Small Stellated Dodecaedru la MathWorld.
en "Another way to construct a great stellated dodecaedru via cumulation is to make 20 triangular pyramids [...] and attach them to the sides of an icosaedru." Eric W. Weisstein, Great Stellated Dodecaedru la MathWorld.
