In recent work the author presented a formal expansion for lambda_dassociated to the dimer problem on a d-dimensional rectangular lattice.Expressed in terms of d it yielded a presumed asymptotic expansion for lambda_din inverse powers of d. We also considered an expansion in powers of x, aformal variable ultimately set equal to 1. We believe this series has betterasymptotic properties than the expansion in inverse powers of d. We discussthis, and apply the same method to the two-dimensional triangular and hexagonallattices. Viewed as a test of the x-expansion the results on those two latticesare satisfactory, if not thoroughly convincing.
