## Abstract A systematic method is established for computing the coupling coefficients associated with arbitrary compact groups using only the general properties of the coefficients and the specific character theory of the relevant groups. The basic character theory is first outlined. Then a primit

To obtain explicit algebraic formulas for calculating 3n-j symbols, a new algebraic method due to Labarthe shows great promise. The method is based on Bargmann's treatment of the rotation group, and Jucys' analysis of vector coupling graphs. In this article we present an overview of Labarthe's algeb

## Abstract The various orthogonality and sum rules which the 6__j__ and 3__jm__ symbols satisfy are sufficient to obtain the algebraic formulas for these symbols for __SO__~3~ โŠƒ __SO__~2~. Character theory enters in that the __j__'s and __m__'s occurring in the various sums are given by the triang
