 | Cupola-Drilled Truncated Icosidodecahedron |
This model, made from Geomag, is a
truncated icosidodecahedron with a
pentagonal cupola (Johnson solid J5) and then a
pentagonal antiprism
excavated from all twelve of its
decagonal faces, and then further drilled by a central
rhombicosidodecahedron, creating holes
through the model. It has a genus of 11.
As with all true Stewart Toroids, the faces are all regular and do
not intersect each other. There are 20 hexagons, 120 squares and
200 equilateral triangles for a total of 340 faces. Stewart mentioned this one
in his book Adventures Among the Toroids, but didn't show a picture.
