Crystallographic vector
WebDefinition (D 2.6.2) A matrix A is called orthogonal if . The name comes from the fact that the matrix part of any isometry is an orthogonal matrix if referred to an orthonormal basis. In crystallography most matrices of the crystallographic symmetry operations are orthogonal if referred to the conventional basis.

The reflection generated by vector a has the form a (x)=−a−1xa = x⊥ −x , (14) where x = x· aa−1 is the component of x along a and x⊥ = x∧aa−1 is the component of x orthogonal to a, as illustrated in Fig. 1. Every vector a is normal to a hyperplane through the origin determined by the equation
