Table 4 The prototypes and their symmetries. The prototypes are grouped into the 14 Bravais lattices: triclinic (tri), monoclinic, (mcl), base-centered monoclinic (mclc), orthorhombic (orc), base-centered orthorhombic (orcc), face-centered orthorhombic (orcf), body-centered orthorhombic (orci), tetragonal (tet), body-centered tetragonal (bct), hexagonal (hex), rhombohedral (rhl), simple cubic (cub), face-centered cubic (fcc), and body-centered cubic (bcc).
