2024 is…
the 22nd tetrahedral number. That is, $2024=\dfrac{22\cdot23\cdot24}6$.
What does this mean, though?
If you had a pyramid of spheres with a triangular base with side lengths of $22$, and stacked each one such that it was stable, there would be $2024$ spheres total. It's like those fruit pyramids one may or may not see at a supermarket. In addition, since $2024=\dbinom{24}3$, it actually appears on Pascal's Triangle! Neat!
