It is widely used for indexing of powder pattern throughout the world and is believed to be one of the most powerful engines for solving high and medium symmetries. It is useful as well for low symmetry at the cost of rather high time consumption 苏五长 有一太苏 玉 长 TREOR This program uses the exhaustive approach.
