A strong coupling limit of theories whose low-energy effective field theory is 5-dimensional N=8 supergravity is proposed in which the gravitational coupling becomes large. It is argued that, if this limit exists, it should be a 6-dimensional theory with (4,0) supersymmetry compactified on a circle whose radius gives the 5-dimensional Planck length. The sector corresponding to the D=5 supergravity multiplet is a (4,0) D=6 superconformal field theory based on the (4,0) multiplet with 27 self-dual 2-forms, 42 scalars and, instead of a graviton, a fourth-rank tensor gauge field satisfying a self-duality constraint. The superconformal field theory has 32 supersymmetries and 32 conformal supersymmetries and its dimensional reduction gives the maximal supergravity in five dimensions. Electromagnetic duality generalises to a gravitational triality.

Very extended Kac Moody algebras and their interpretation at low levels (2003, methodology): “This required formulation differs from the one discussed in a five-dimensiona; context in [25, 26].”
Survey of two-time physics (2000, background): “One can also include OSp(8∗|8) discussed recently [32] in the list of interesting algebras contained in OSp(1|64) (with some contraction) as being relevant for describing some corners of “M-theory”.”
