### Description

We present new symmetric cumulant measurements, as well as two-, four- and six-particle $v_n$ measurements (and their ratios) for charged and particle identified hadrons. These measurements will be presented for a broad range of transverse momenta and centrality intervals in U+U collisions at $\sqrt{s_{NN}}$= 193 GeV and Au+Au, Cu+Au, Cu+Cu, d+Au and p+Au collisions at $\sqrt{s_{NN}}$=200 GeV. The measurements indicate the expected trends for hydrodynamic-like viscous attenuation in the medium produced in the different systems, the influence of initial-state fluctuations, system shape ($\varepsilon$), system-size and asymmetry, and the transport coefficients ($\eta/s$, $\zeta/s$, ... ) on the flow coefficients ($v_n$). The measurements are also compared to viscous hydrodynamic calculations to pin down the roles of initial-state fluctuations, mixed harmonic correlations and system size and shape ($\varepsilon$). The implication of these measurements for understanding the medium properties of these systems will be discussed.
