A projective confined configuration E with axis and centre will be introduced in terms of a non-degenerate octagon O satisfying some hypotheses on the position of its diagonal points (i.e. intersections of edges having distance 8 in the flag graph F(Β£?)) and its first minor diagonal lines (i.e. diag

In this paper we show that blocking sets of cardinality less than 3(q Ο© 1)/2 (q Ο­ p n ) in Desarguesian projective planes intersect every line in 1 modulo p points. It is also shown that the cardinality of a blocking set must lie in a few relatively short intervals. This is similar to previous resul

A dual blocking set is a set of points which meets every blocking set but contains no line. We establish a lower bound for the cardinality of such a set, and characterize sets meeting the bound, in projective and affine planes. A blocking set for a family ~-of sets is a set which meets every member
