Description
By analogy to 3D gravity, I present an attempt to get a hold of diffeomorphisms in lattice tetrad gravity: diffeomorphisms can be replaced by combinations of Lorentz and Shift symmetries, all of which can be covariantly defined, eliminating the seperation into spatial and timelike constraints.
I present these results, their implications for corner symmetries as well as some early ideas for how to implement these symmetries on a phase space toy model that includes discretised tetrads (edge vectors) explicitly.
