1859Cayley Math. Papers (1891) IV. 83 On account of the stellation é = 2. 1938H. S. M. Coxeter et al. Fifty-Nine Icosahedra i. 1 We enumerate and describe the polyhedra that can be five Platonic solids by stellation, i.e., by extending or ‘producing’ the faces until they meet again, always preserving the rotational symmetry of the original solid. 1948― Regular Polytopes xiv. 264 The first stellation of {ob}5, 3, 3{cb} is constructed by stellating the 720 pentagons into {ob}5/2{cb}'s, and the 120 dodecahedra into {ob}5/2, 5{cb}'s. The result is {ob}5/2, 5, 3{cb}. 1971Sci. Amer. Dec. 114/2 The five Platonic solids are complete of their symmetrical kind. By mixing regular polygon faces, however, Archimedes made 13 more solids. These can be variously extended by putting cells on faces, called stellation, or by cutting away cells whenever that process can reveal new regular polygon faces within. |
