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 Ο½ 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.
First we define relations between the u = (s\* + s + 1) (s + 1) flags (point-line incident pairs) of a finite projective plane of order s. Two flags a E (p, 1) and b = (p', l'), where p and p' are two points and 1 and 1' are two lines of the projective plane, are defined to
