The important role of Hadamard designs for applications in several fields has been long established. A considerable problem of finite geometry is to determine the configuration of the minimum number of points that block a design, i.e. the shape of a minimum set of points which have at least one point in common with any block.

Abstract
The important role of Hadamard designs for applications in several fields has been long established. A considerable problem of finite geometry is to determine the configuration of the minimum number of points that block a design, i.e. the shape of a minimum set of points which have at least one point in common with any block. In this paper we del with Hadamard 3-designs blocked by only four points.File allegati a questo prodotto
