The known examples of embedded unitals (i.e. Hermifian arcs) in PG(2, qZ) are B-unitals, i.e. they can be obtained from ovoids of PG(3, q) by a method due to Buekenhout. B-unitals arising from elliptic quadrics are called BM-unitals. Recently, BM-unitals have been classified and their collineation g

We give a characterization of the Buekenhout-Metz unitals in PG(2, q2), in the cases that q is even or q = 3, in terms of the secant lines through a single point of the unital. With the addition of extra conditions, we obtain further characterizations of Buekenhout-Metz unitals in PG(2, q2), for all

## Abstract An affine 2–(__q__^3^,__q__^2^, __q__ + 1) design is constructed from a Buekenhout‐Metz unital of the affine plane AG(2,__q__^2^), with __q__ > 2. It is also shown that such a design is isomorphic to the point‐plane design of the affine space AG(3,__q__). Β© 2003 Wiley Periodicals, Inc.
