Separating Thickness from Geometric Thickness
<|reference_start|>Separating Thickness from Geometric Thickness: We show that graph-theoretic thickness and geometric thickness are not asymptotically equivalent: for every t, there exists a graph with thickness three and geometric thickness >= t.<|reference_end|>
