A geometric construction of a (38,2)(38,2)-blocking set in PG(2,13)PG(2,13) and the related [145,3,133]13[145,3,133]13 code

An (l,n)(l,n)-blocking set S   in PG(2,q)PG(2,q) is a set of l   points such that every line of PG(2,q)PG(2,q) intersects S in at least n points, and there is a line intersecting S in exactly n   points. In this paper we give a geometrical construction of a (38,2)(38,2)-blocking set in PG(2,13)PG(2,13).
