Let \(\Lambda\) denote an extended Dynkin diagram with vertex set \(\Lambda_0=\{0,1,\ldots, n\}\). For a vertex \(i\), denote by \(S(i)\) the set of vertices \(j\) such that there is an edge joining \(i\) and \(j\); one assumes  the diagram has a unique vertex \(p\), say \(p=0\), with \(|S(p)|=3\)....
