Research supported by the National Science Foundation *l Ref \[2\]g ives the upsdon total width to three-loop and ref \[3\]g wes 3(g) to three loops mous increase in computational power. This letter presents those new features of our calculation which can be usefully apphed m many other QED or QCD calculations.

N2 - We present a powerful method for evaluating Feynman amplitudes involving fermions which interact through gauge bosons. Implementing our procedure on a computer, we have evaluated the O(αs4) and O(αs5) five- and six-quark scattering amplitudes required to predict exclusive hadron scattering amplitudes in QCD.
