title: Identification of and symmetry computation for crystal nets.
abstract: Exact methods are presented to determine whether two periodic nets are combinatorially isomorphic and to compute the full combinatorial symmetry group of a net. It is found that for a large class of nets, which includes all known zeolite nets and most other known crystal nets, this group can be realized as a crystallographic space group.
