AbstractLower bounds are given for the number of lines blocked by a set of q + 2 points in a projective plane of order q. Implications are discussed to the theory of blocking sets and bounds are obtained for the size of a double intersecting set of circles in a Möbius plane
We obtain lower bounds for the size of a double blocking set in the Desarguesian projective planePG(...
