7-demicube (Pyritohedral)
Posted on July 16, 2026
A physical model of the projection with pyritohedral symmetry of Gosset's 1_41 Polytope, much more difficult to build than its model with icosahedral symmetry.
All-Blue projection of the 6-Cube
Posted on June 13, 2026
Nan Ma found five 3D projections of the 6-cube which could be built with Zometool struts of the same color. Paulo Freire already made physical models of three of these. Here the "blue" 6-cube is presented.

A Zometool implementation of another vZome model from Nan Ma's treasure trove of zomeable H3-symmetric polytope projections.
Gosset's 2_31 Polytope

A Zometool implementation of Nan Ma's vZome model for the H3-symmetric projection of this 7D polytope.
Larger subset 10-cube projection
Posted on June 19, 2025
A larger selection of the Icosahedral projection of the 10-cube, reproducing about 60% of the total number of struts.
Small subset 10-cube projection
Posted on June 16, 2025
A selection of the Icosahedral projection of the 10-cube, revealing several non-intersecting polyhedra with icosahedral symmetry.
Icosahedral Projections of 6-demicube
Updated on May 3, 2025
Zometool models for both icosahedral projections of the 6-demicube, following the guidelines of Paulo Freire.
Compound of 6-cube and 6-orthoplex
Posted on April 30, 2025
Paulo Freire made Zometool models of the icosahedral projections of both the 6-cube and its dual, the 6-orthoplex. Here I present the building instructions for the compound of both in one single model.
10-cube

Only to know how many struts building a physical model would require, all crossing struts in Scott's implementation of the Icosahedral projection of the 10-cube, have been replaced by intersecting struts.
Gosset's 4_21 Polytope
Posted on April 15, 2025
An adaptation of Scott's implementation of the Gosset's 4_21 polytope. Both the elimination of overlapping struts and the replacement of crossing struts by intersecting half-blue struts has been performed programmatically. No attempt has been made to build this monster.

An adaptation of Scott's implementation of the Gosset's 3_21 polytope.
Gosset's 2_21 Polytope

Yet another adaptation of Scott's implementation of a Gosset's polytope.
