# Click number of a graph according to its order and average degree

Let $$G$$ be simple graphic order $$N$$and let $$bar {d}$$ to be his average degree.

1. Find the maximum value of $$omega (G)$$ (the number of cliques $$G$$) as a function of $$N$$ and $$bar {d}$$.

2. Find the minimum value of $$omega (G)$$ as a function of $$n$$ and $$bar {d}$$.

3. What are the minimum and maximum values ​​of $$omega (G)$$ when $$G$$ is $$d$$-ordinary?
