✦ Synopsis
We prove that the number of directions determined by a set of p points in AG(2, p), p prime, cannot be between ( p+3)Â2 and ( p&1)Â2+ 1 3 -p. This is equivalent to saying that besides the projective triangle, every blocking set of Re dei type in PG(2, p) has size at least 3( p&1)Â2+ 1 3 -p.
