✦ Synopsis

A geometric construction of a symmetric primitive association scheme of rank 6 on the antiflags of a finite projective plane is given. This scheme allows one to reconstruct the initial plane up to isomorphism and polarity. It is shown that for a Desarguesian plane the corresponding scheme is non-Schurian.

In this paper we describe an algorithm for computing the dual of a projective plane curve. The algorithm requires no extension of the field of coefficients of the curve and runs in polynomial time.
