### Abstract

A new precision lattice simulation set is analyzed for the equation of state to sixth order. We used lattice results at imaginary chemical potentials to calculate the Taylor coefficients, from which the pressure, trace anomaly, energy and entropy density as well as the baryon number can be derived. We discuss an alternative extrapolation strategy and show first results for zero strangeness chemical potential.
