Pearson symbol represents crystal system, type of Bravais lattice and number of atoms in an unit cell. For instance, a facecentered cubic (FCC) structure is a facecentered Bravais lattice having 4 atoms in the unit cell, and thus its Pearson symbol is cF4. In this notation, the crystal system is simplified by a = triclinic, m = monoclinic, o = orthorhombic, t = tetragonal, h = hexagonal and trigonal and c = cubic. The Bravais lattice is symbolized by P, S (for A, B and C), R, F and I. Table 2954a. Symbols used in Pearson notation.
