摘要：
It is known that commutative twisted field planes of odd order have orthogonal polarities, and, for square orders, also unitary polarities, see Dembowski (Finite Geometries, Springer, Berlin, 1968). In this paper, the associated ovals and unitals are considered and their collineation groups are determined. (C) 1999 Elsevier Science B.V. All rights reserved.
