AB - For the first time, correlations among mixed-order moments of two or three flow harmonics —(v<inf>n</inf><sup>k</sup>,v<inf>m</inf><sup>l</sup>) and (v<inf>n</inf><sup>k</sup>,v<inf>m</inf><sup>l</sup>,v<inf>p</inf><sup>q</sup>), with k, l , and q denoting the respective orders—are measured in xenon–xenon (XeXe) collisions and compared with lead–lead (PbPb) results, providing a novel probe of collective behavior in heavy ion collisions. These measurements compare a nearly spherical, doubly-magic <sup>208</sup>Pb nucleus to a triaxially deformed <sup>129</sup>Xe nucleus, emphasizing the sensitivity to initial-state geometry fluctuations arising from nuclear deformation. The dependence of these results (v<inf>n</inf> , n=2,3,4) on the shape and size of the nuclear overlap region is studied. Comparisons between v <inf>2</inf>, v <inf>3</inf>, and v <inf>4</inf> demonstrate the importance of v <inf>3</inf> and v <inf>4</inf> in exploring the nonlinear hydrodynamic response of the quark-gluon plasma (QGP) to the initial spatial anisotropy. The results constrain initial-state model parameters that influence the evolution of the QGP. The CMS detector was used to collect XeXe and PbPb data at nucleon-nucleon center-of-mass energies of S<inf>NN</inf>=5.44 and 5.36 TeV, respectively. Correlations are extracted using multiparticle mixed-harmonic cumulants (up to eight-particle cumulants) with charged particles in the pseudorapidity range | η | ' 2.4 and transverse momentum range 0.5 ' p<inf>T</inf> ' 3 GeV/c.
