This is the highest order accessible by finite temperature perturbation theory applied to a non-Abelian gauge theory before the high-temperature infrared catastrophe. All ultraviolet divergences are eliminated by renormalization of the vacuum, the HTL mass parameters, and the strong coupling constant. The three-loop results for the pressure and trace anomaly are found to be in very good agreement with recent lattice data down to \$T 2-3\$ \$T\_c\$, which are temperatures accessible by current and forthcoming heavy-ion collision experiments.
