We report machine learning evidence for the existence of the intermediate hexatic phase in this system, and extract the critical exponent $\\nu\\approx0.65$ for the divergence of the correlation length of the associated solid-hexatic phase transition. Moreover, we clarify the discontinuous nature of the hexatic-liquid phase transition in this system.
