Show that if $G$ is a graph with $|E| \geq 2|V|^{3/2}$, then $G$ must contain a $4$-cycleCan someone explain/point me in the right direction on this?Let's say we say $|V|= 4$, using the equation above we get $|E|= 16$.I drew it out and I was unable to come up with $16$ edges. Do I completely misunderstand the graph equation?
