  New bispectral polynomials orthogonal on a quadratic bi-lattice are obtained
from a truncation of Wilson polynomials. Recurrence relation and difference
equation are provided. The recurrence coefficients can be encoded in a
perturbed persymmetric Jacobi matrix. The orthogonality relation and an
explicit expression in terms of hypergeometric functions are also given.
Special cases and connections with the para-Krawtchouk polynomials and the
dual-Hahn polynomials are also discussed.
