Variations on a theme of Cofman


Abstract


En
The paper provides a survey on the known results on the collineation groups acting on a line of a projective plane with some transitivity properties. As a new result, it is shown that a group which is faithful and primitive of rank 3 on a line of a projective plane is 1-dimensional semilinear.
