Due to a never-ending tale of woe with broken computers I haven't got access to Stella at the moment...
You know the "deltahedron" - same edges as the regular dodecahedron, pentagonal dimples each comprising 5 equilateral triangles, the polyhedron is actually a stellation of the icosahedron?
If ...

Re: Cundy & Rollett
Indeed, if you don't have internal braces of some kind or stiffen the paper somehow, the finished five-cubes paper model has an annoying tendency to "pop in" at its octavalent re-entrant vertices.
If you use double tabs and continue the tabs where the edges form pentagrams - do it pin-wheel style ...

As far as 4D OFF is concerned, they can be read in without cells or edges being defined, as this is what HEDRON produces. It does fail without faces though.
A 3D OFF with vertices only does work as that was the method I used to generate a number of the sub-zonohedrifications of the dodecahedron at ...

Re: Six pentagrammatic prisms
Here's the compound of six with dodecahedral symmetry.
And I couldn't resist making the compound of twelve by merging the six with its mirror image. :o Same set of 60 corners, now two prisms per each:

Re: Six pentagrammatic prisms
Yes! I meant six...Dinogeorge wrote:Are you sure you don't mean six pentagrammatic prisms? Five of those prisms have only 50 corners, a number that doesn't evenly divide 120, the order of the icosahedral symmetry group.
