By employing Monte Carlo HYDJET++ model (HYDrodynamics plus JETs), we produce anisotropic harmonic flow coefficients 
(n = 4–7) in deformed Xe–Xe collisions at = 5.44 TeV. We measure these harmonics with respect to a plane constructed using lower-order Fourier harmonics 
and 
(produced using reaction plane method). The cross-talk of elliptic and triangular flows in the model generates both even and odd harmonics of higher order. By combining analyses of higher harmonics with analyses of and , one can eliminate the uncertainty in modeling anisotropic flow from initial conditions and define quantities that only involve nonlinear hydrodynamic response coefficients. In this process, we study the individual response of higher-order flow coefficients to the lower-order flow coefficients through a power-law (relation 
) scaling technique as a function of collision centrality. We report that these higher-order flow coefficients (n = 4–7) are centrality dependent and strongly correlated with elliptic and triangular flow. The results are compared with data from recent ALICE, ATLAS and CMS experiments at LHC.
