We consider the D 6 R 4 ?> term which is the leading contribution in the low momentum expansion of the three loop, four graviton amplitude in maximal supergravity. We calculate the moduli dependent coefficient of this term in eleven dimensional supergravity compactified on T2. Only diagrams that involve the Mercedes skeleton contribute resulting in a compact expression involving an integral over six Schwinger parameters. We express this integral as an integral over the moduli of an auxiliary T3…

Novel cancellations not predicted by traditional superspace power-counting arguments render its degree of divergence in D dimensions no worse than that of N=4 super-Yang-Mills theory--a finite theory in four dimensions.
