By deriving PG(2, q<sup>2</sup>) with respect to a derivation set disjoint from U we obtain a new unital Uā² in the Hall plane of order q<sup>2</sup>. We show that this unital contains O'Nan configurations and is not isomorphic to the known unitals of the Hall plane, hence it forms a new class of unitals in the Hall plane.enA class of Buekenhout unitals in the Hall planeJournal article0030006483001996383610.36045/bbms/11055407622-s2.0-003993020770489Barwick, S.
