    "abstract": "Exact solvability of the discretized N-point version of the PT-symmetric\nsquare-well model is pointed out. Its wave functions are found proportional to\nthe classical Tshebyshev polynomials of a complex argument. At all N a compact\nsecular equation is derived giving the real spectrum of energies at any\nnon-Hermiticity strength Z below its finite and weakly N-dependent critical\nvalue. In the limit of vanishing Z the model degenerates to a Hermitian Hueckel\nHamiltonian.",
