The influence of elliptic and triangular flow on higher flow harmonics is studied within the HYDJET++ model, which merges parametrized hydro with jet quenching. Even harmonics can be generated by elliptic flow only, while odd harmonics need nonzero triangular component. A hydrodynamical model predicts a scaling of υ4/υ22 ratio with pT, while jets force a rise of the high pT tail of the ratio. Hexagonal flow appears to be an interesting interplay between υ2 and υ3. It shows a dominant contribution of υ3 in central events and υ2 at more peripheral collisions. Comparison with ALICE, ATLAS and CMS experimental data is presented.
