Two-particle cumulant with reference particles chosen from the FMD and 4-particle cumulant with reference particles chosen from the TPC in Pb-Pb collisions at $\sNN{} = 5.02\,\TeV{}$. The pseudorapidity separations are $|\Delta \eta | > 2.0$ and $3.8$ for two-particle cumulants for mid and forward rapidities, respectively. For the $v_{2}\{4\}$ the separations are $|\Delta \eta | > 0$ and $2.0$ for mid and forward rapidities, respectively. At mid rapidity, the results are extrapolated to $\pT=0$. AMPT and CLVisc model calculations are compared with the results.
