21. For example, for Heisenberg spin chains, where the z component of the total magnetization S tot z is conserved, M would be the number of overturned spins starting from a fully ferromagnetic reference state.
22. This is correct as long as a degree of flexibility is maintained in what we mean with a wavefunction of Bethe ansatz form. An example that comes to mind is the Heisenberg spin chain at roots of unity (Refs.), where a complete set of states includes wavefunctions which can be viewed as given by the derivative of a Bethe ansatz.

26. In Bethe ansatz as in many other things, the devil is in the details: the generalized Pauli principle is not strictly valid (see cited literature in Ref.) in its most basic formulation, but can be made so by an appropriate cataloguing of string states, including (over)deformed strings.
27. U (2) symmetry in the case of the isotropic chain, and the loop algebra symmetry for the gapless chain at roots of unity] and can be treated in the ABACUS logic by, for example, introducing additional levels.

29. Such pictorial representations of quantum numbers and of their movement when scanning through the set of eigenstates are reminiscent of a traditional ABACUS and suggested the name of the library.

31. ij 9, making the above labeling unambiguous.
32. For the specific case of the one-dimensional Bose gas, a different convention is used, in which sectors 1/3 and 2/0 are permuted.
