   <hidden TTP07-17  The four-loop DRbar beta-functions for general gauge groups. > We present four-loop results for the gauge beta-function and
 the fermion mass anomalous dimension for a gauge theory
 with a general gauge group and a multiplet of fermions
 transforming according to an arbitrary representation, calculated
 using the dimensional reduction scheme. In the
 special case of a supersymmetric theory we confirm
 previous calculations of both the gauge beta-function and
 the gaugino mass beta-function.
