Explicit result for an arbitrary term of the expansion is obtained in terms of log-sine integrals. Construction of the epsilon-expansion in the three-point case is also discussed.7 pages, latex, contribution to the Proceedings of AIHENP-99 (Heraklion, Crete, Greece, April 1999)High Energy Physics - TheoryHigh Energy Physics - PhenomenologyMathematical Physicstext
