What is Delone Sets: Local Identity and Global Symmetry about?

In the paper we present a proof of the local criterion for crystalline structures which generalizes the local criterion for regular systems. A Delone set is called a crystal if it is invariant with respect to a crystallgraphic group. So-called locally antipodal Delone sets, i.e. such sets in which all 2R-clusters are centrally symmetrical, are considered. It turns out that the local antipodal sets have crystalline structure. Moreover, if in a locally antipodal set all 2R-clusters are the same the set is a regular system, i.e. a Delone set whose symmetry group operates transitively on the set.
