Alternative proofs were given by Tutte [Tut63a] and Wessel [Wes86] Beineke and Harary [BH65] showed the formula for #(Kn ) for most cases, and Alekseev and Goncakov [AG76] and, independently, Vasak [Vas76] completed the result: #(Kn ) # n 7 6 # for n # 1, n #= 9, n #= 10 #(K 9 ) #(K 10 ) 3 For the complete bipartite graph, the thickness is still not settled for ....

....be reassigned arbitrarily in the plane without altering the topology of the planar embedding provided we are allowed to bend the edges at will [10] This observation is easily verified by induction, moving one vertex at a time. The (graph theoretical) thickness is now known for all complete graphs [1, 2, 3, 12, 13], and is given by the following formula: Kn ) 8 : 1; 1 n 4 2; 5 n 8 3; 9 n 10 Sigma n 2 6 Upsilon ; n 10 (1:1) Another notion related to geometric thickness is the book thickness of a graph G, bt(G) defined as follows [4] A book with k pages or a k book , is a ....

....the visibility number of an n vertex graph G, it is tempting to use Remark 1 and express G as a union of planar graphs, since planar graphs have visibility at 7 most 2. When n is not 9 or 10, every n vertex graph is the union of at most b(n 7) 6c planar graphs, with equality for cliques (see [1] for n 6j 4 mod 6, with the remaining case settled through the work of many authors) This yields about n=3 as an upper bound on visibility number of n vertex graphs. Using planar graphs whose cut vertices lie on one face, which seems feasible, could eliminate the factor of 2 between this and the ....
