9711 Želetava           Discovered 1972 Aug. 7 by P. Wild and I. Bauersima at Zimmerwald.
Bearing a 13:12:5 Pythagorean relationship to (8964) [Corvus] Corax and (3735) Třeboň, (9711) Želetava is a small Moravian town near the center of the hypotenuse of a similar triangle with short leg centered on Třeboň, Bohemia, and long leg running through Vranov (crow, Corvus), Moravia, and Raabs (raven, Corax), Austria.
