Talk:Great stellated dodecahedron

Uh, where are the pentagrammic faces? Professor M. Fiendish, Esq. 02:55, 29 August 2009 (UTC)

They are sneaky - here's one yellow face show on each! Tom Ruen (talk) 03:02, 29 August 2009 (UTC)

Is "stellated dodecahedron" the correct nomenclature?
I am no expert on the nomenclature of stellated regular solids.

But this sure looks to me like a stellated icosahedron rather than a stellated dodecahedron.

Why should it be called a stellated "dodecahedron"?


 * Yes, it's the correct name. It's a common misconception that stellation just means to add a spike on each face. I'd call that augmentation. Stellation means creating a new polyhedron whose faces lie in the same planes as the original polyhedron. In this case its pentagrammic faces lie in the same planes as the faces of a regular dodecahedron. The great dodecahedron is also a stellation of the dodecahedron, and the great icosahedron is a stellation of the regular icosahedron. But stellations are often spiky, hence the confusion. Another way of thinking of it is: if you cut along each facial plane, what would you be left with in the middle. RobertCWebb (talk) 13:34, 14 October 2023 (UTC)
