The (7-3) structure

The (7-3) structure consists of equilateral triangular prisms and parallelepiped hexahedrons. The packing fraction is increased by small spheres penetrating slightly into the interior of triangular prisms. The structural data of the (7-3) structure at several radius ratios: $0.463$, $0.465$, $0.468$, $0.471$, $0.474$, $0.477$, $0.480$, $0.481$, $0.482$, $0.483$, and $0.485$, are downloadable here. The root directory contains several directories, which correspond to the several radius ratios. The structural data files are named by their packing fractions.
