Provided that no particles have spins higher than 2, maximal supergravities are defined to be with supergravities with 32 supersymmetries.(adsbygoogle = window.adsbygoogle || []).push({});

Why is theN=8 supergravity in four dimensions called 'the maximal supergravity'? I am confused now....

Thanks.
