   <hidden TTP02-02  Two-loop matrix elements for three jet production: the $n_f$ contribution. >     We discuss the calculation of the
     $n_f$-contributions to the two-loop
     amplitude for $ e^+ e^- \rightarrow q g \bar{q}$.
     The calculation uses an efficient method based on nested sums.
     The result is presented in terms of multiple polylogarithms
     with simple arguments, which allow for analytic continuation 
     in a straightforward manner.
