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.
