Correlations between moments of different flow coefficients are measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV recorded with the ALICE detector. These new measurements based on multiparticle mixed harmonic cumulants calculated using charged particles pseudorapidity region $|\eta|<0.8$ transverse momentum range $0.2 < p_{\rm T} 5.0$ GeV/$c$. The centrality dependence correlations two as well three coefficients, both terms their second moments, shown. In addition, a collection involving higher $v_2$ and $v_3$ is for first time, where characteristic signature negative, positive negative signs four-, six- eight-particle observed, respectively. compared to hydrodynamic calculations iEBE-VISHNU AMPT TRENTo initial conditions.
