Abstract
The talk briefly reviews the current state of the art in doing multilo op QCD calculations in a completely analytic way. In particular, we di scuss recent analytical calculations of 4-loop O(alpha(s)(3)) gluino c ontribution to R(s) and its implications to Gamma(tot)(Z --> hadrons) and Gamma(tau(-) --> nu(tau) + hadrons);.
