We present high-precision measurements of elliptic, triangular, and quadrangular flow v(2), v(3), and v(4), respectively, at midrapidity for identified hadrons pi, p, K, phi, K-s, Lambda as a function of centrality and transverse momentum in Au+Au collisions at the center-of-mass energy root s(NN) = 200 GeV. We observe similar v(n) trends between light and strange mesons which indicates that the heavier strange quarks flow as strongly as the lighter up and down quarks. The number-of-constituent-quark scaling for v(2), v(3), and v(4) is found to hold within statistical uncertainty for 0-10%, 10-40%, and 40-80% collision centrality intervals. The results are compared to several viscous hydrodynamic calculations with varying initial conditions, and could serve as an additional constraint to the development of hydrodynamic models.
