These three conics are all hyperbolas, and have a common center T→ +, which is
the forward Brocardian point of the Tarry point T , and is the midpoint between
the common points F→ + and F→ −. In other words, F→ +F→ − is a common diameter
of the three hyperbolas. We remark that the Tarry point T is the point X 98 of
[3], and is the fourth intersection of the Kiepert hyperbola and the circumcircle of
triangle ABC. The fact that 1 and 2 intersect at T→ follows from the observation
that these lines are respectively the loci of the forward Brocardians of points on the
Kiepert hyperbola
