[math-fun] "Net" of a dodecahedron
This look wrong to anyone else? https://commons.wikimedia.org/wiki/File:Geometric_Net_of_a_Regular_Dodecahed... -- -- http://cube20.org/ -- [ <http://golly.sf.net/>Golly link suppressed; ask me why] --
Yeah, that's dead wrong. It forces some pairs of pentagons to share two edges, and an order-4 vertex is obvious in that rhombic gap. On Tue, Aug 2, 2016 at 5:29 PM, Tom Rokicki <rokicki@gmail.com> wrote:

This having been said, I can't find any pages that reference this howler. The pictures in the "Dodecahedron" article on Wikipedia proper all look correct. And "What links here" says nothing does. On Tue, Aug 2, 2016 at 5:34 PM, Allan Wechsler <acwacw@gmail.com> wrote:

Good eyes Tom! The two "hemispheres" have to be joined differently, and just along one edge (not two). -Veit

I wonder how many different correct nets there are? On Wed, Aug 3, 2016 at 10:17 AM, James Buddenhagen <jbuddenh@gmail.com> wrote:
