The growth rate of items per day may may seem absurd, but it's actually much less than the acceleration in the 12 Days of Christmas song.

For one, it looks to me like the triangle numbers, which for triangle number T~n~ = (n+1) choose 2.

So for a correct nested advent calendar of 24 days, it's T~24~ = (24+1) choose 2 = 300

Also, it appears that they created the terminal function that does that in a very compact notation, so another correct way to write down this sum is "24?" Where n? = n + (n-1)?
