In the present paper we slightly modify the Dynkin–
Minchenko construction of enhanced Dynkin diagrams and construct signed enhanced Dynkin diagrams of exceptional types Φ =
E6, E7, E8. We observe that these diagrams contain as subdiagrams
all Carter–Stekolshchik diagrams of conjugacy classes of the Weyl
groups W(Φ).
