Self-interacting, self-avoiding polymer chains and rings are generated on the f.c.c. lattice by exact enumeration. The effect of the 'good' solvent is represented by a short-range repulsive interaction between pairs of polymer units. The partition function and the moments of the end-to-end distance and mass distributions are extrapolated to obtain the limiting behaviour at various temperatures. Difficulties encountered in determining the exponents and their temperature dependence are discussed.
