Ž . w Ž .x ) P PT T invariance of complex potentials V x s V yx combines their real symmetry with imaginary antisymmetry. Ž . Ž We describe a new exactly solvable model of this type. Its spectrum proves real, discrete and 'three-fold', ´s ´j s 2 n n . 2 q a , n s 0,1, . . . , with a G 0 and j s 1,2,3.
