Your compass is your best friend; even as the storm tosses your ship
like a wayward duck, it always keeps its cool. It's almost as reliable
as the good ol' sun, which always shows itself at daybreak no matter
how fierce the gale. As you look back at your sundial before
approaching the beautiful island, you marvelled at the beautiful
shadow triangle it forms. Looking at the shadow, you hear three geniuses in
your group, Sroyon, Debmalya, and Satwata, in intense conversation. You
find out that they are arguing about the following problem.
Consider an arbitrary triangle on the plane. Let $n$ be a possible
number of laminar axes of symmetry the triangle may have. Find out all
the possible values of $n$.
Arrange the possible values of $n$ in ascending order, and
concatenate them; what is the result? For example, if you think that
the possible values of $n$ are $10$, $8$, $9$, and $3$, then your
answer should be $38910$.
