1st Stellation of the Icosahedron


Some don't really think of this is a 'stellation' as such, but it falls within the generic scheme of creating the stellations and it is therefore known as the first stellation. (Another scheme regards this as the 'zero-th' stellation and counts the rest up to 58!)

I had diagrams for this one, but it turned out to be a rediscovery of a unit by Tomoko Fuse, so I removed it. Sorry!

Other diagrams

There are a large number of icosahedron models. Most are modular (Tomoko Fuse, Miyuki Kawamura etc.) but there are a few single sheet versions (John Montroll, Kazuo Haga)
