We calculate the five-loop contribution to the quark bi-linear, ghost, gluon and quark field anomalous dimension for the minimal momentum subtraction (mMOM) scheme when fixed in the linear covariant gauge. The coupling constant gauge parameter plane is then analysed for fixed points with the corresponding critical exponents evaluated. which is used to consider bounds on the conformal window.
