Description	The domain D of all the coupling strengths compatible with the reality of the energies is studied for a family of non-Hermitian N x N matrix Hamiltonians H-(N) with tridiagonal and PT-symmetric structure. At all dimensions N, the coordinates are found of the extremal points at which the boundary hypersurface partial derivative D touches the circumscribed sphere (for odd N = 2M + 1) or ellipsoid (for even N = 2K).
