Petersen graphs are a type of graph that are often used to explore patterns in data. /CropBox [0 1.44 414.39999 642] Someone's about to get it! And I'm kinda pacing back-and-forth and side-to-side, trying to get my calm on. The degree of every vertex must be even, since for each vertex \(x\), the number of edges exiting \(x\) equals the number of edges entering \(x\). Hes not playing a particularly smart game (a few errors tonight highlight that) but he is playing a very entertaining game. Leonhard Euler settled this problem in 1736 by using graph theory in the form of Theorem 5.13. Kuratowski's Theorem proof . Prove that Petersen's graph is non-planar using Euler's There is an Euler path in a connected graph if and only if the number of vertices of odd degree is 0 or 2. However, this implies that, \(C = (x_1,x_2,x_3,,x_i,x_t,x_{t-1},x_{t-2},,x_{i+1})\).
