Building on a strategy introduced in arXiv:1706.05364, we present exact analytic expressions for all the singlet eigenstates and eigen-values of the simplest non-linear (n = 2, d = 3) gauged Gurau-Witten tensor model. This solves the theory completely. The ground state eigenvalue is-2�14 in suitable conventions. This matches the result obtained for the ground state energy in the ungauged model, via brute force diagonalization on a computer. We find that the leftover degeneracies in the gauged theory, are only partially accounted for by its known discrete symmetries, in-dicating the existence of previously unidentified "hidden" global symmetries in the system. We discuss the spectral form factor, the beginnings of chaos, and the distinction between theories with SO(n) and O(n) gaugings. Our results provide the complete ana-lytic solution of a non-linear gauge theory in 0+1 dimensions, albeit for a specific value of N. A summary of the main results in this paper were presented in the companion letter arXiv:1802.02502. © 2019 International Press of Boston, Inc.
