Query: Bannai-Ito polynomials and dressing chains   Schur-Delsarte-Genin (SDG) maps and Bannai-Ito polynomials are studied. SDG
maps are related to dressing chains determined by quadratic algebras. The
Bannai-Ito polynomials and their kernel polynomials -- the complementary
Bannai-Ito polynomials -- are shown to arise in the framework of the SDG maps.
