A general algorithm which generates all the topologically distinct, linked, non-Hartree-Fock vacuum and Greenfunction Hugenholtz-type diagrams is presented. Both the particle-hole and particle-particleGreen-functions are considered. The one-particle Green function diagrams are not treated separately

## Nature of physical problem Computations of Feynman diagrams in non-Abelian gauge field theories involves the group-theoretic weight computation. The present program implements the Cvitanovic algorithm [2] of computation of the group-theoretic weight for SU( n) and SO(n). ## Restriction on the
