DESCRIPTION:Large gauge symmetries of asymptotically flat Einstein gravity
  in 4 dimensions are extremely well understood. The asymptotic symmetry gr
 oup is infinite dimensional\, and the Ward identities of the associated ch
 arges lead to the infinitely many soft theorems of gravitational scatterin
 g. These infinitely many soft theorems exist in 6 dimensions as well. Howe
 ver\, the construction of the corresponding charges has long remained elus
 ive.\nIn this talk I will present a way of constructing a consistent phase
  space of asymptotically flat Einstein gravity in 6 dimensions. In contras
 t with previous work\, this phase space allows for the existence of super-
 rotations. Furthermore\, I will explain how one can normalize the associat
 ed charges using an ambiguity in the symplectic form of gravity.
