The authors have calculated explicitly the complete algebra of the tetrad gravity constraints which are directly related to the group manifold approach, including all possible contributions which were previously overlooked in the literature. The resulting algebra closes and the structure functions are found to coincide with those written in earlier works only on the constraint surface.

Abstract
The authors have calculated explicitly the complete algebra of the tetrad gravity constraints which are directly related to the group manifold approach, including all possible contributions which were previously overlooked in the literature. The resulting algebra closes and the structure functions are found to coincide with those written in earlier works only on the constraint surface. The additional terms contain both undifferentiated and differentiated delta functions.
