I guess it was somewhere around 1995 that I derived this model from the Trapezoidal Icositretrahedron, which is the dual of a Rhombicubocatahedron. I calculated the model by hand, including the pieces I needed to build a model of it. I built two models. I was not so satisfied with the material I used for the first one, so I built this one afterwards. The first one I gave away.

The whole model is a compound of 12 cubes with cube symmetry. I used four
colours to indicate that the model consists of four of the same compounds of
3 cubes. It is a special form of
12*B*|*S*_{4}x*I|C*_{2}x*I*, where the
model consists of 4x3|*D*_{12} as described in H.F.Verheyen's
Symmetry Orbits.
