Nature of problem:
Computations of Feynman diagrams in non-Abelian gauge field theories involves the group-theoretic weight computation. The present program implements the Cvitanovic algorithm of computation of the group- theoretic weight for SU(n) and SO(n).

The available computer memory is the severest restriction.

Running time:
Strongly depends on a concrete form of the diagram. The running time of test examples is 4 to 40 sec. on the computer EC-1040.
