We investigate the entanglement properties of symmetry states of the Schur-Weyl duality. Our approach based on reduced two-qubit density matrices, and concurrence as the measure of entanglement. We show that all kinds of “entangled graphs", which describe the entanglement structure in Schur-Weyl states are completely coded in the corresponding Young tableau.
