Great dodecahemidodecahedron (dual polyhedron) |
|
In geometry, the great dodecahemidodecacron is the dual of the great dodecahemidodecahedron, and is one of nine dual hemipolyhedra. It is appears indistinct from the great icosihemidodecacron.
Since the great dodecahemidodecahedron has six decagrammic faces passing through the model center, the great dodecahemidodecacron has six vertices at infinity. In Magnus Wenninger's Dual Models, they are represented with intersecting infinite prisms passing through the model center, cut off at a certain point that is convenient for the maker.
