| Abstract: | 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”  . However, the treewidth of  was not determined exactly. We determine the exact treewidth of the line graph of a complete graph. |
