3D Net of Truncated Tesseract (19-Tat)
The truncated tesseract is number 19 in the list of uniform polychora in
with the abbreviated name "tat". It has 24 cells:
8 truncated cubes (orange) and
16 tetrahedra (red). This model represents an
unfolded net for the 4D polytope, that is, the cells have been unfolded from 4D
back to a "flat" 3D model. This kind of models can help us to understand how
these polytopes fit together.
See this tutorial for some comments on
obtaining nets for building paper models of 4D polytopes.
Here is what the model would look like folded up, if we had a fourth
dimension in which to fold it. Four orange cells have been hidden to
reveal internal detail. Can you see how it would fold up?
