Give an example of a graph G of order 6 and size 10 such that δ(G) = 3 and Δ(G) = 4�Can I do like this??

    How are $δ(G)$ and $Δ(G)$ defined? – 2017-02-22

$V=\{a,b,c,d,e,f \}$

$E=\{(a,d),(a,e),(a,f),(b,d),(b,e),(b,f),(c,d),(c,e),(c,f),(a,b) \}$

All vertices have degree $3$ except for $a$ and $b$ which have degree $4$.
