Abstract: In 1985, the famous graph theory expert Erdês and Neíet ilconjectured that strong edge2coloring number of a graph is bounded above by 5 4 Δ2 whenΔ is even and 1 4 (5Δ2 - 2Δ + 1) whenΔ is odd. They gave a graph ofΔ = 4. In this paper, we construct a series of such graphs. and p rove that if the Strong Edge Coloring Con2 jecture is correct, the boundary number is op timum.
