Best way to express 2014 In my class, I always write the date using mathematical formulas, or cool little equations. I want to show my students that even the most mundane seeming number often has fascinating features, and its own beauty - that's the reason I got into mathematics, and I want to pass it down.

For example, for 30, I wrote $\frac{6!}{4!}$.

Now, 2014 has kind of stumped me. The best I could come up with was this, using factorials:

$$(2!(2!+2!(4!))+3!)(4!-3!+1!)$$

But, this isn't the most attractive, or interesting, equation.

What do you think the best (nerdiest?) way to write 2014 is?
Looking $2014$ up in the OEIS turns up:

$$2014=13^3-13^2-13^1-13^0$$

In general, looking a number up in the OEIS is probably a reasonable way to turn up pleasing identities.
If anyone went to HCSSiM, we have a tradition of worshiping the number $17$. 

So I would say the coolest way to express $2014$ is $$2014=2 \times 19 \times 51$$ 

It is easy to show that this neat fact: $2014$ is in fact the smallest number that can be expressed as a product of three distinct positive integers that are all congruent modulo $17$.
