  In this proceedings contribution we present a recent three-loop
hard-thermal-loop perturbation theory (HTLpt) calculation of the thermodynamic
potential for a finite temperature and chemical potential system of quarks and
gluons. We compare the resulting pressure, trace anomaly, and
diagonal/off-diagonal quark susceptibilities with lattice data. We show that
there is good agreement between the three-loop HTLpt analytic result and
available lattice data.
