Minimal blocking sets in PG(2,q) arising from a generalized construction of Megyesi
We generalize the Megyesi construction for Rédei minimal blocking sets by placing cosets of a multiplicative subgroup of GF(q)\{0} on n lines of the affine plane.These points together with the determined directions give a minimal blocking set B with |B| ≥ (2 -2/9)q + O( √ q).We also investigate some …
