Barwick, S.O'Keefe, C.2006-06-192006-06-191997Journal of Geometry, 1997; 58(1-2):43-520047-24681420-8997http://hdl.handle.net/2440/3609We show that if U is a Buekenhout-Metz unital (with respect to a point P) in any translation plane of order q² with kernel containing GF(q), then U has an associated 2-(q², q + 1, q) design which is the point-residual of an inversive plane, generalizing results of Wilbrink, Baker and Ebert. Further, our proof gives a natural, geometric isomorphism between the resulting inversive plane and the (egglike) inversive plane arising from the ovoid involved in the construction of the Buekenhout-Metz unital. We apply our results to investigate some parallel classes and partitions of the set of blocks of any Buekenhout-Metz unital. © Birkhäuser Verlag, Basel, 1997.enJournal article0030006468001997054010.1007/BF012229252-s2.0-5324908647570474Barwick, S.
