How to get a 600-cell
In the three-dimensional space 5 tetrahedra can't share an edge because there will be a small hole between them. We can "fold them up" in the four-dimensional space and this will be the first step of the construction of the 600-cell, that is one of the six regular polytopes in dimension 4.
