Hi Robin,

I am sure you can combine these with Stella by just adding the compounds as described below, but I let Robert answer that, since I am not familiar with Stella.

I uploaded a zip file (temporarily) on my own site with the two models shown:
https://tunnissen.eu/tmp/14_cubes.zip

Here I used the 6 | S4xI /D2xI version, there is also a version 6 | S4xI / C4xI where you have a rotational freedom. In that case I would use an angle that will evenly divide when adding the extra cube, i.e.mu=30 degrees.... Hmm, actually because to the classical compound of 3 cubes, one more is ad...

You can also put together 1, 3, 4, and 6 to get 14 cubes. This looks as follows: https://i.postimg.cc/LqqnSKGy/14-cubes.png In that case you will not be able to the the 15th of course Here I used the 6 | S4xI /D2xI version, there is also a version 6 | S4xI / C4xI where you have a rotational freedom....

I used the nomenclature from Verheyen's book "Symmetry Orbits"

Here is a picture of both version (A and B) together


I call them "Mr and Mrs"

Thanks Robert.

I thought we could gather models for compound polyhedra. I don't know why, but I like compound polyhedra and I built quite a few (well, relatively) of them. This is the latest one I built: https://i.postimg.cc/Q9JfVWKR/10-A-A5x-I-D3x-I.jpg It is referred to as 10A | A5xI / D3xI. I guess a 3D is quic...

The following pages contain some more info about these compounds: http://www.tunnissen.eu/polyh/tetrahedra-compounds.vrml.html http://www.tunnissen.eu/polyh/cubecmps.vrml.html http://www.tunnissen.eu/polyh/octacmps.vrml.html Since VRML is hopelessly outdated, I also have pages that use Javascript t...

I finished the model. This time I succeeded. It's a relief that I succeeded this time. Apparently this was not my Nemesis. :wink: Here is a picture into an order 5 symmetry axis: https://i.postimg.cc/McBSXNZ7/A5-hepta-twister.jpg For my next project I am thinking to build a compound of 15 cubes. htt...

Yesterday evening I suddenly remembered that I made another model with transparent faces. One that isn't a polychoron. This one: http://tunnissen.eu/polyh/heptagons/pics/hepta.GD.A5xI.jpg It consists of equilateral heptagons that look like regular heptagons. I made this one transparent, because othe...

Hi Ulrich Here is a zip-file with 24 examples of polyhedra that only consist of regular heptagons. I found more of these, but some are quite messy and I didn't include them here. I just noticed that one off-file of a model that I built is missing. I also found polyhedra that have other regular polyg...

Some of you might know that I am interested in heptagons. The background for this interest is that if you ignore polyhedra with prism and anti-prism symmetry then the heptagon forms the first gap of polygons for which there aren't any uniform polyhedra. Even if you look at the Johnson solids, where ...

What glue did you use? I found that it just peeled off later. Nothing fancy, really. In the picture below I show the glues I used. The Karlsons (yellow) is the one I used. Nowadays I use the other one (Casco, black). Cannot explain why, I just think it is a better glue. It did happens sometimes tha...

Thanks, Robert

Still no go (and I have a FB account). It says for me (in Swedish) that the page doesn't exist
