. The inversion of a horn torus is a Horn Cyclide (or Parabolic Horn Cyclide). The above left figure shows a horn torus, the middle a cutaway,and the right figure shows a Cross-Section of the horn torus through the 
-plane.See also Cyclide, Horn Cyclide, Ring Torus, Spindle Torus, Standard Tori, Torus
