    Description
    It is shown that the correlator of four stress-energy tensors in N=4 SYM has only two independent amplitudes instead of six, and that these can be read off from an N=2 hypermultiplet correlation function. Using harmonic superspace methods it is demonstrated that the quantum corrections to the remaining two amplitudes are proportional. The strong-coupling expression obtained in a recent supergravity calculation is simplified and found to be of the predicted form.
