All homogeneous sphere packings were derived that refer to the trivariant lattice complexes of monoclinic space‐group types P 2/ c and P 2 1 / c . In total, sphere packings of 55 types have been found. The maximal inherent symmetry is monoclinic for 17 types while the other types comprise at least one sphere packing with cubic (four cases), hexagonal (six cases), tetragonal (eight cases) or orthorhombic (20 cases) symmetry.
