✦ Synopsis


We obtain an infinite class of simple non-algebraic matroids of rank 3, the minors of which are vector matroids and therefore algebraic. We prove that the matroids are nonalgebraic with the aid of a theory of harmonic conjugates in full algebraic combinatorial geometries .

Any finite partial plane J, and thus any finite linear spa~e and any (simple) rank-three matroid, can be embedded into a translation plane. It even turns out, that o¢ is embeddable into a projective plane of Lenz class V, and that the characteristic of this plane can be chosen arbitrarily. In partic
