THIS COORDINATE SET COMPRISES TWO CHAINS REPRESENTING REMARK 3 TWO CHEMICALLY EQUIVALENT, BUT CRYSTALLOGRAPHICALLY DISTINCT, REMARK 3 ENTITIES. THE OTHER HALF OF THE COMPLETE TETRAMER MAY BE REMARK 3 GENERATED FROM THIS DIMER BY THE APPLICATION OF THE REMARK 3 CRYSTALLOGRAPHIC DIAD PARALLEL TO Z THROUGH THE ORIGIN OF THIS REMARK 3 COORDINATE SYSTEM, I.
