Let P be a finite projective plane of arbitrary odd order n, and let π be a regular polarity of P: that is, a polarity for which there exists an integer s = s(π) such that every line containing two or more absolute points of π contains s + 1 absolute points [11, p. 247J. Baer [1] has shown that the absolute points form an oval when n is odd and nonsquare, and Segre [13] has shown that every oval in a Desarguesian projective plane is a conic.
