How do you find the number of edges on a graph?
The maximum number of edges possible in a single graph with 'n' vertices is ⁿC₂ where ⁿC₂ = n(n – 1)/2. The number of simple graphs possible with 'n' vertices = 2ⁿc₂ = 2ⁿ⁽ⁿ^-¹^)/².
What is the formula for number of edges in a grid graph?
Hence, the number of edges of an m×n grid graph is Em×n grid=m(n?1)+(m?1)n=mn?m+mn?n=2mn?m?n.

There is no simple graph having a degree sequence (1, 3, 3, 3, 5, 6, 6)
Handshaking Theorem:
Commenting on the statement of the Handshaking theorem, we can say that according to this theorem, the number of edges on the graph is half the sum of degrees of the vertices.
