After reduction to 5D they all share the fiel d content of standard maximal supergravity. While so far these theories ar e only known in the free limit\, their interacting versions were conjectur ed by C. Hull to exist and to describe strong coupling limits of N=8 theor ies in 5D. \n\nI present novel actions in a 5+1 split of coordinates whose field equations reproduce those of the free bosonic (4\,0) and (3\,1) the ory\, respectively\, including the selfduality relations. I discuss eviden ce for a master exceptional field theory formulation with an extended sect ion constraint that\, depending on the solution\, produces the (4\,0)\, (3 \,1) or the conventional (2\,2) theory.\n LOCATION:https://researchseminars.org/talk/EGSS/16/ END:VEVENT END:VCALENDAR
