Abstract : We designed a quantum circuit to prepare a permutation-symmetric maximally entangled three-qubit state called the
 
 
 
 
 
 
 state and experimentally created it on an NMR quantum processor. The presence of entanglement in the state was certified by computing two different entanglement measures, namely negativity and concurrence. We used the
 
 
 
 
 
 
 state in conjunction with a set of maximally incompatible local measurements, to demonstrate the maximal violation of inequality number 26 in Sliwa's classification scheme, which is a tight Bell inequality for the (3, 2, 2) scenario,
 i.e.
 , the three-party, two-measurement-settings and two-measurement-outcomes scenario.
