Let X, G be a primitive commutative association scheme. If g g G is nonsym-ลฝ . metric of valency 4, then the graph X, g is uniquely determined up to isomorphism. In particular, the cardinality of X is the cube of an odd prime. แฎ 1999 ## X Let r : X = X be given. We set < r\* [ x, y y, x g r , ร 4
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-Sch
