Small hexacronic icositetrahedron

In geometry, the small hexacronic icositetrahedron is the dual of the small cubicuboctahedron. It is visually identical to the small rhombihexacron. A part of each dart lies inside the solid, hence is invisible in solid models.

gollark: PwnCC *said* something about a zero-day, but I'm not entirely sure about that one since it was never demonstrated. I still don't recommend running it except on stuff you don't need much and can easily stick in a disk drive for formatting.
gollark: I meant "probably nobody bothered much".
gollark: Probably.
gollark: I do think it's at least resonably secure though.
