In 2019, Jung-Weber gave an example of a concrete magic unitary M, which defines a C^*-algebraic model of the quantum permutation group S₄^+. We show with the help of a computer that there exist no polynomials up to degree $50$ separating the entries of M from the generators of C(S₄^+). This indicates that the magic unitary M might already define a faithful model of S₄^+.
