ParryPoint

The Parry point is one of the two intersections of the Parry circle and the circumcircle of a triangle (the other is the focus of the Kiepert parabola, which is Kimberling center X_(110)). The Parry point is Kimberling center X_(111) and has triangle center function

alpha_(111)=a/(2a^2-b^2-c^2)

(Kimberling 1998, pp. 227-228).
