   <hidden TTP96-55  Automatic Computation Of Three-Loop Two-Point Functions In Large Momentum Expansion > We discuss the calculation of two-point three-loop functions with an
 arbitrary number of massive propagators and one large external momentum. The
 relevant subdiagrams are generated automatically.  The resulting
 massless two-point integrals and massive tadpoles are transformed
 on-line to FORM-expressions ready to be used by existing FORM packages
 which calculate them analytically.  As an example we compute the
 quartic mass corrections to the photon polarization function.
