dual of H-stellation of icosahedron,|
H-faceting of dodecahedron,
vertex figure of paphacki,
|Circumradius||sqrt(3)/2 = 0.866025|
|General of army||v-doe|
Even so hudsi is more directly been seen as a faceting of the dodecahedron, it well can be considered dually as being related to a stellation of the icosahedron. For the latter the du Val namings of complete shells, being used in turn within the set of "the fifty-nine [stellated] icosahedra", got known as a standard. The former lack such a standard. This is why the acronym is based on the dual figure.
As an abstract polyhedron hudsi is isomorph to dudsi, thereby maintaining the q-edges, but replacing the f-edges by v-edges, resp. replacing the triangular faces from being pip vertex figures into being stip vertex figures. – It then still remains vertex inscribed into a v-doe.
