DESCRIPTION:Using positivity bootstraps we address random (unitary invaria
 nt) tensors in the large-N limit. As has been done for unitary invariant r
 andom matrices\, we combine the Dyson-Schwinger equations and positivity c
 onstraints of moments to approximate the moments one quartic and two hexic
  rank three tensor models. All models studied converge quickly\, and for t
 hose which have known analytic formulae\, they converge to such solutions.
  We conjecture new explicit formulae for all moments of the rank three qua
 rtic model and support several conjectures\, both using bootstrapped resul
 ts and by explicit double-series computations obtained with 'feyntensor'.
