 Multiplicity dependence of $v_n\{k\}$ for \pp, \pPb, \XeXe\ and \PbPb\ collisions. Statistical uncertainties are shown as vertical lines and systematic uncertainties as filled boxes (coloured online) Data are compared with PYTHIA 8~ simulations (solid lines) of pp collisions at $\sqrt{s} = 13$ TeV and IP-Glasma+MUSIC+UrQMD~ calculations of pp, \pPb, \PbPb\ collisions at $\snn = 5.02$ TeV and \XeXe\ collisions at $\snn = 5.44$ TeV (filled bands - coloured online) (a)~$v_2$, $v_3$ and $v_4$ measured using two-particle cumulants with a pseudorapidity gap greater than $1.4$ or $1.0$ units (b)~$v_2$ measured using multi-particle cumulants, with the 3-subevent method for the four-particle cumulant, and 2-subevent method for higher order cumulants in \PbPb\ collisions.
