%X We present sets of symmetry average points in the Brillouin zone from which the average over the Brillouin zone of a periodic function of wave vector can be determined easily. The calculation accuracy is comparable to that of special points, but the calculation labour is reduced considerably. The symmetry average points for crystals with cubic and hexagonal Bravais lattices are given and the calculation accuracy is illustrated numerically through an real example.
