Hi all! I was just wondering how to construct a dodecadodecahedron. Why isn't a net given? --116.14.72.74 (talk) 10:09, 26 July 2009 (UTC)

The nets can be constructed with Stella (software). Here's this one. You need 12 pentagrams and 20 rhombic clusters. Tom Ruen (talk) 10:21, 26 July 2009 (UTC)

## Misplaced sentence

The convex hull of the dodecadodecahedron is an icosidodecahedron.

It looks like sentence must be in other place - not in Medial rhombic triacontahedron section.

Or it must be rplaced by The convex hull of the medial rhombic triacontahedron is an icosahedron. Jumpow (talk) 13:48, 28 November 2015 (UTC)

It is correct as stated, but was mentioned previously. I think the point is that since the two are duals, the convex hull of one is the dual of the stellation core of the other. So I'll reword it accordingly. Double sharp (talk) 17:15, 28 November 2015 (UTC)
Why we talk about the convex hull of the dodecadodecahedron in section about Medial rhombic triacontahedron? In that place we may talk about convex hull of the medial rhombic triacontahedron or have to remove this sentence at all. Jumpow (talk) 17:58, 28 November 2015 (UTC)

## Co-ordinates?

Why doesn't this article give the Cartesian co-ordinates of the solid, as the articles on many other polyhedra do?

I am trying to construct a 3D model (.obj file), and attempted to do so by calculating the midpoints of the edges of a dodecahedron. However, something seems to have gone wrong with my calculation; the shape formed by the first few vertices seems to be an elongated one.

Same as Icosidodecahedron#Cartesian_coordinates. Tom Ruen (talk) 03:12, 16 June 2017 (UTC)
