The Dynkin–Minchenko construction of enhanced Dynkin diagram is slightly modified to construct signed enhanced Dynkin diagrams of exceptional type Φ = E6, E7, E8. It is observed that these diagrams contain as subdiagrams all Carter–Stekolshchik diagrams of conjugacy classes of the Weyl groups W(Φ).
