摘要：

We construct the six-point, next-to-maximally-helicity-violating one-loop amplitude in N = 4 supergravity using unitarity and recursion. The use of recursion requires the introduction of rational descendants of the cut-constructible pieces of the amplitude and the computation of the nonstandard factorization terms arising from the loop integrals.
