摘要：

In a previous paper [1], all point sets of minimum size in PG(2,q), blocking all external lines to a given irreducible conic C, have been determined for every odd q. Here we obtain a similar classification for those point sets of minimum size, which meet every external and tangent line to C. (c) 2004 Wiley Periodicals, Inc.
