WebNov 29, 2024 · In general it will require some thought on whether a degree sequence is that of a planar graph. For example, see this question for some possible strategies, which include using Kuratowski's Theorem, or the well known edge bound $3n - 6$. You can also compute the average degree, which for a planar graph must be strictly less than 6. WebNext we have a similar graph, though this time it is undirected. Figure 2 gives the pictorial view. Self loops are not allowed in undirected graphs. This graph is the undirected …

A simple graph is called maximal planar if it is planar but adding any edge (on the given vertex set) would destroy that property. All faces (including the outer one) are then bounded by three edges, explaining the alternative term plane triangulation.
