Abstract: We demonstrate that it is possible to determine the coefficients of anall-order beta function linear in the anomalous dimensions using as data thetwo-loop coefficients together with the first one of the anomalous dimensionswhich are universal. The beta function allows to determine the anomalousdimension of the fermion masses at the infrared fixed point, and the resultingvalues compare well with the lattice determinations.
