We show how the sharp constant for the L²-L⁶ adjoint restriction estimate for the circle can be obtained by combining a sharp estimate for a trilinear operator with signed kernel and modelled on double convolutions of measures supported on circles, together with the positive semidefinitiveness of the Laplacian matrix of some signed weighted graphs associated to the discretization of the problem obtained by Fourier series decomposition.
