Comment (by ncohen):
By the way: it seems to me that, theoretically speaking, having breadth
`>=b` is equivalent to:
{{{
sage: G1 = my_lattice.hasse_diagram().transitive_closure()
sage: G2 = posets.BooleanLattice(p).hasse_diagram().transitive_closure()
sage: G1.subgraph_search(G2,induced=True)
True
}}}
But well. Does not seem like it would help on the computational side.
