A new lower bound for the size of an affine blocking set

Abstract

A blocking set in an affine plane is a set of points B such that every line contains at least one point of B. The best known lower bound for blocking sets in non-desarguesian affine planes was derived in the 1980’s by Bruen and Silverman. In this note, we improve on this result by showing√ that a blocking set of an affine plane of order q, q  25, contains at least (Formula presented) points.
