## Abstract In a previous paper 1, all point sets of minimum size in __PG__(2,__q__), blocking all external lines to a given irreducible conic ${\cal C}$, have been determined for every odd __q__. Here we obtain a similar classification for those point sets of minimum size, which meet every externa

We obtain lower bounds for the size of a double blocking set in the Desarguesian projective plane PG(2, q). These bounds are best possible for q Ͻ 11 and in the case q is a square. With the same technique we also exclude certain values for the size of an ordinary minimal blocking set.
