NJGRAF — An efficient program for calculation of general recoupling coefficients by graphical analysis, compatible with NJSYM. NJGRAF calculates angular momentum recoupling coefficients by graphical methods. The results are sums of products of 6j coefficients. These can be evaluated several times with different values of the arguments. The number and the range of summation variables are minimal. It is intended to replace NJSYM, with a gain of computer time of up to two orders of magnitude.
