Program “color” for computing the group-theoretic weight of Feynman diagrams in non-Abelian gauge theories

Abstract Title of program: COLOR Catalogue number: AAXC Program obtainable from: CPC Program Library, Queen's University of Belfast, N. Ireland (see application form in this issue) Computer: IBM 360/370 Operating system: OS, VM Programming language used: REDUCE [1] High-speed storage required: depends on the problem; minimum about 400 Kbytes Number of bits in word: 32 Number of lines in combined program and test deck: 200 Title of program: COLOR Catalogue Id: AAXC_v1_0 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).
