  7. For lattice size ≫|R|≫ lattice spacing these conditions lead to a four-spin interaction ∼ log |R| for two-dimensional models and ∼ 1/|R| for three-dimensional models.

The four-spin interaction is highly anisotropic and exists only for spins on the same line of atoms in which case it is ∼ |R| in the range of note (7) For lattice size ≫ |R| ≫ lattice spacing these conditions lead to a four-spin interaction ∼ log |R| for two-dimensional models and ∼/|R| for three-dimensional models.
