Abstract

BLOCKING SET IN PG (N, Q) IS A SET OF POINTS THAT HAS NONEMPTY INTERSECTION WITH EVERY HYPERPLANE OF PG(N, Q). A BLOCKING SET THAT CONTAINS A LINE IS CALLED TRIVIAL. A BLOCKING SET IS CALLED MINIMAL IF NONE OF ITS PROPER SUBSETS ARE BLOCKING SETS. A COVER C FOR A GROUP G IS CALLED A ŸN-COVER WHENEVER C IS AN IRREDUNDANT MAXIMAL CORE-FREE N-COVER FOR G AND IN THIS CASE WE SAY THAT G IS A ŸN-GROUP.IN THIS PAPER WE GIVE RELATIONS BETWEEN BLOCKING SETS AND &NBSP;ŸN-GROUPS.
