Recently a matrix model with non-pairwise index contractions has been studied in the context of the canonical tensor model, a tensor model for quantum gravity in the canonical formalism. This matrix model also appears in the same form with different ranges of parameters and variables, when the replica trick is applied to the spherical-spin model () in spin glass theory. Previous studies of this matrix model suggested the presence of a continuous phase transition around, whereanddesignate its matrix size. This relation betweenandintriguingly agrees with a consistency condition of the tensor model in the leading order of, suggesting that the tensor model is located near or on the continuous phase transition point and therefore its continuum limit is automatically taken in thelimit. In the previous work, however, the evidence for the phase transition was not satisfactory due to the slowdown of the Monte Carlo simulations. In this work, we provide a new setup for Monte Carlo simulations by integrating out the radial direction of the matrix. This new strategy considerably improves the efficiency, and allows us to clearly show the existence of the phase transition. We also present various characteristics of the phases, such as dynamically generated dimensions of configurations, cascade symmetry breaking and a parameter zero limit, and discuss their implications for the canonical tensor model.
