Mathematically, the points of the diamond cubic structure can be given coordinates as a subset of a three-dimensional integer lattice by using a cubic unit cell four units across. With these coordinates, the points of the structure have coordinates (x, y, z) satisfying the equations x = y = z (mod 2), and x + y + z = 0 or 1 (mod 4). There are eight points (modulo 4) that satisfy these conditions: WebIf the crystal is cubic then all the facets are [100]. A cube have six similar surface which are called [100] facets.
