We argue that N=8 supergravity in four dimensions exhibits an exceptional E8(8) symmetry, enhanced from the known E7(7) invariance. Our procedure to demonstrate this involves dimensional reduction of the N=8 theory to d=3, a field redefinition to render the E8(8) invariance manifest, followed by dim...
