Abstract: We construct a Gröbner Basis of the relation ideal of a polynomial and give an interpolation formula for the basis elements which is sufficiently explicit to be used in practical computations. We prove a constructive version of a theorem of Galois, concerning the solvability of rational polynomials of prime degree. For a number of example polynomials, the computations are carried out.
