In this limit, two entangled copies of the SYK model have a bulk description of sorts known as the \"chord Hilbert space.\" We analyze a symmetry algebra acting on this Hilbert space, generated by the two Hamiltonians together with a two-sided operator known as the chord number. This algebra is a deformation of the JT gravitational algebra, and it contains a subalgebra that is a deformation of the $\\mathfrak{sl}_2$ near-horizon symmetries.
