Have you heard of an omnitruncated dodecaplex?
On January 25, Prof. Benoit Charbonneau is working with students to build a 4D object. This mathematical artefact, called an omnitruncated dodecaplex, will be built using Zometool pieces.
Once completed, the project will hang permanently in the atrium of the Mathematics 3 building.

What is a Omnitruncated Dodecaplex?
A polytope is a finite convex region of space enclosed by a finite number of hyperplanes. In two dimensions, we refer to this as a polygon. In three dimensions, a polyhedron.
The dodecaplex (aka 120-cells) is a convex regular four-dimensional polytopes built from 120 dodecahedral cells. It has 720 pentagonal faces, 1,200 edges and 600 vertices. The omnitruncated dodecaplex that is being built is an orthogonal projection of a four-dimensional polytope constructed by truncating all vertices, edges, and faces of the dodecaplex.
This “barn raising” of the omnitruncated dodecaplex is an opportunity for students to learn in a hands-on manner about the geometry. It’s also a piece of art that will proudly hang in the Mathematics 3 atrium.
After we complete the build, watch the model rise to its permanent spot - suspended from the ceiling in the M3 Atrium.
Volunteers will be making a valuable and memorable contribution to the legacy of the Faculty of Mathematics.
