Query: Direct Connection between the R_{II} Chain and the Nonautonomous
  Discrete Modified KdV Lattice   The spectral transformation technique for symmetric R_{II} polynomials is
developed. Use of this technique reveals that the nonautonomous discrete
modified KdV (nd-mKdV) lattice is directly connected with the R_{II} chain.
Hankel determinant solutions to the semi-infinite nd-mKdV lattice are also
presented.
