A004030 Number of n-dimensional Bravais lattices.
(Formerly M3847)
1, 1, 5, 14, 64, 189, 826 (list; graph; refs; listen; history; text; internal format)



In 1850, Bravais demonstrated that crystals were comprised of 14 different types of unit cells: simple cubic, body-centered cubic, face-centered cubic; simple tetragonal, body-centered tetragonal; simple monoclinic, end-centered monoclinic; simple orthorhombic, body-centered orthorhombic, face-centered orthorhombic, end-centered orthorhombic; rhombohedral; hexagonal; and triclinic.
