Regular Bipartite Lattices with Large Values of Theta_2,2,2/C_4
(10K, LaTeX)
ABSTRACT. The quantities C_4 and Theta_2,2,2 are as defined by Wanless,
C_4 just the number of 4-loops of a graph.
The construction of this paper provides a counterexample to a conjecture of
Butera, Pernici, and the author about the monomer-dimer entropy,
lambda, of a regular bipartite lattice.
