In fact, the template of the proof is going to very much mirror what we already did for the log star analysis by Hopcroft and Ullman. So in that spirit, let's review what were the two basic workhorses, the two building blocks that drove forward the Hopcroft-Ullman analysis.

"WebAbstract. Let G be any n -vertex planar graph. We prove that the vertices of G can be partitioned into three sets A, B, C such that no edge joins a vertex in A with a vertex in B, neither A nor B contains more than 2 n / 3 vertices, and C contains no more than 2 2 n vertices. We exhibit an algorithm which finds such a partition A, B, C in O ( n ... " - Hopcroft-tarjan algorithm

In 1974, a significant breakthrough was achieved when Hopcroft and Tarjan, using path addition and depth first search, presented an algorithm to test planarity in linear time [HT74]. Still, this algorithm only returns whether a graph is planar, but it does not actually find the planar
