Query: Rigged Configurations Approach For The Spin-1/2 Isotropic Heisenberg
  Model   We continue the rigged configurations analysis of the solutions to the Bethe
ansatz equations for the spin-1/2 isotropic Heisenberg model. We analyze the
non self-conjugate strings of Deguchi-Giri and the counter example for the
string hypothesis discovered by Essler-Korepin-Schoutens. In both cases clear
discrete structures appear.
