  By specializing the parameters in the partition function of the 8VSOS model
with domain wall boundary conditions and diagonal reflecting end, we find
connections between the three-color model and certain polynomials $p_n(z)$,
which are conjectured to be equal to certain polynomials of Bazhanov and
Mangazeev, appearing in the eigenvectors of the Hamiltonian of the
supersymmetric XYZ spin chain. This article is a continuation of a previous
paper where we investigated the related polynomials $q_n(z)$, also conjectured
to be equal to polynomials of Bazhanov and Mangazeev, appearing in the
eigenvectors of the supersymmetric XYZ spin chain.
