The statement n^2 + 9 + 9 is known as "cDonald's Theorem" and when plotted on a graph models a uniformly curved line that somehow joins up with itself.

This is a figure which science has yet to come up with a name for. Can you think of one? If you can, the Royal Mathematics Society would like to hear from you!
