  The 3-regular graphs representing sums over products of Wigner 3-jm symbols
are drawn on up to 12 vertices (complete to 18j-symbols), and the irreducible
graphs on up to 14 vertices (complete to 21j-symbols). The
Lederer-Coxeter-Frucht notations of the Hamiltonian cycles in these graphs are
tabulated to support search operations.
