AbstractWe show that the upperbound for the number of nuclei of a q + 1-set in the Desarguesian affine plane of order q, and the Jamison-Brouwer/Schrijver lower-bound for the size of a blocking set in the same plane are consequences of a single theorem
A blocking set in an affine plane is a set of points B such that every line contains at least one po...
