In three dimensions, the gluon condensate of pure SU(3) gauge theory hasultraviolet divergences up to 4-loop level only. By subtracting thecorresponding terms from lattice measurements of the plaquette expectationvalue and extrapolating to the continuum limit, we extract the finite part ofthe gluon condensate in lattice regularization. Through a change ofregularization scheme to MSbar and (inverse) dimensional reduction, this resultwould determine the first non-perturbative coefficient in the weak-couplingexpansion of hot QCD pressure.Comment: 11 page
