Abstract
Perturbative coefficients for Wilson loops and the static quark self-energy are extracted from Monte Carlo simulations at large beta on finite volumes , where all the lattice momenta are large. The Monte Carlo results are in e xcellent agreement with perturbation theory through second order. New resul ts for third order coefficients are reported. Twisted boundary conditions a re used to eliminate zero modes and to suppress Z(3) tunneling.
