The spinor structure associated with the local gauge group GL(4,R) of the nonsymmetric gravitation theory (NGT) is based on a spinor wave equation constructed from a vierbein, a GL(4,R) spin connection, and the infinite-dimensional irreducible representations of the universal covering group S-scriptL-script (4,R) of the noncompact group SL(4,R). The multiplicity-free irreducible representations of S-scriptL-script (4,R) correspond to bivalued spinorial representations of SL(4,R) that contain an infinite number of half-odd integer spin particles. By adjoining the translations T/sub 4/, the extended group A-script = T/sub 4/ x GL(4,R) replaces the Poincare group P-script. The properties of the mass spectrum are obtained from an infinite-component wave equation and the physical spinor field consists of an infinite sum of finite, nonunitary representations of the Lorentz group.
