Named after Auguste Bravais (1850), there are 5 distinct Bravais lattices in two dimensions, 14 in three dimensions, and 64 in four dimensions.
Combining the seven 3D lattice systems with primitive (P), base-centered (S), body-centered (I), and face-centered (F) centering yields the 14 3D Bravais lattices.
Every physical crystal structure is formed by placing a basis of one or more atoms or molecules at each discrete point of a Bravais lattice.
