How to get the net of a 120-cell
We can get a net of the 120-cell (one of the six regular polyhedra in dimension 4) from a pile of 10 dodecahedra and surround it with 10 rings of 5 dodecahedra each, as in the figure. We get a larger pile of 60 dodecahedra and if we attach two of these piles, we have a net.
