However note that there is an extra degree of freedom (besides scale): the ratio of square edge to triangle edge. Perhaps adjust this so that the total surface areas of cube faces and of octahedral faces become equal? WFL On 7/3/19, Christian Lawson-Perfect <christianperfect@gmail.com> wrote:
I've made a 3d model in OpenSCAD and uploaded it to thingiverse: https://www.thingiverse.com/thing:3726912. I've put a simple rendering of the shape on that page; I'm going to both 3d print it and do a nicer CGI rendering now.

At http://faculty.uml.edu/jpropp/mathenchant/motley-draft3.pdf you'll find a draft of an essay that will be published on July 11th. Comments are welcome, but even more welcome would be a good picture of the "spherical pseudo-cuboctahedron"! In principle I know how to make such a picture, sort of: take the motley dissection of the surface of the cube (shown in the essay), push all the vertices out onto a sphere, and draw spherical arcs joining up those vertices. This seems like a job for Mathematica, but my mastery of 3D graphics isn't up to the job. I'll gratefully acknowledge anyone who can create a picture I can use!
Thanks,
