Densest lattice packing of a truncated cube
The truncated cube has 24 vertices, 36 edges and 14 facets, 6 octagons and 8 triangles. It is one of the thirteen Archimedean solids and its dual is called triakis octahedron. It was rediscovered during th 15th century by the outstanding artist Piero della Francesca.
The density of a densest lattice packing was calculated with the algorithm of Betke and Henk. The density is equal to 0.9737...and the 14 points in the picture show the lattice points of a critical lattice lying in the boundary.
