In recent articles by Grohe and Marx, the treewidth of the line graph of a complete graph is a critical example—in a certain sense, every graph with large treewidth “contains” L ( K n ) . However, the treewidth of L ( K n ) was not determined exactly. We determine the exact treewidth of the line graph of a complete graph.
