We introduce a process called geometric sorting, which can be applied to an arbitrary configuration of points indspace, and which encodes in compact form the order properties of the configuration, just as the arrangement of a set of numbers in size place encodes its order properties. We give an algorithm for carrying out this sorting procedure in time, which generalizes the optimum sorting time offor the linear case; In addition, we give an efficient algorithm for determining whether two randomly numbered configurations inhave the same order type, using a distinguished family of orderings of each. Finally, we indicate how this new concept of sorting can be applied to problems in pattern recognition, stereochemistry, and cluster analysis.
