    "abstract": "Bound states generated by K coupled PT-symmetric square wells are studied in\na series of models where the Hamiltonians are assumed $R-$pseudo-Hermitian and\n$R^2-$symmetric. Specific rotation-like generalized parities $R$ are considered\nsuch that $R^N=I$ at some integers N. We show that and how our assumptions make\nthe models exactly solvable and quasi-Hermitian. This means that they possess\nthe real spectra as well as the standard probabilistic interpretation.",
