Abstract
For pt.I see J. Phys. C, vol.10, no.9, p.1379 (1977). High-field expansions for the Ising model on a honeycomb lattice have been given in terms of mixed one-spin/two-spin/three-spin Ising models on the triangular lattice. It is pointed out that a two-parameter subset of these mixed models has been solved and that the series expansions are thus subject to a large number of constraints.
