摘要：
A c.U*-geometry is a geometry over the diagram c.L*, the point residues of which are finite dual unitals. Only one flag-transitive example is known. Its full automorphism group is Aut(J(2)), but J(2) also acts flag-transitively on it. We shall prove that this geometry is indeed the unique flag-transitive c.U*-geometry, thus obtaining a new geometric characterization of the Hall-Janko group J(2).
