Such factors are analysed in the context of a $sl(6/1)$ supersymmetric model of the genetic code.4 pages LaTex, uses icmp.sty, 2 figures, Contribution to proceedings of oXXII International Colloquium on Group Theoretical Methods in Physics (Group22) Hobart, 13-17 July 1998, to be published by International PressBiological PhysicsQuantitative Biologytext
