Is it possible for the number created by ordering $1$ to $n$ where $n \geq 1$ be a palindrome?
I've been thinking about this problem for a while now, and have come up with nothing useful.
If anybody knows the solution, or the break-through idea, it'll be much appreciated. It's from a Russian 1996 Olympiad:
Can the number obtained by writing the numbers from $1$ to $n$ in order (for some $n>1$) be a palindrome?
