Given is an integer sided triangle $ABC$ with $BC \le AC \le AB$.
$k$ is the angular bisector of angle $ACB$.
$m$ is the tangent at $C$ to the circumscribed circle of $ABC$.
$n$ is a line parallel to $m$ through $B$.
The intersection of $n$ and $k$ is called $E$.

How many triangles $ABC$ with a perimeter not exceeding $100\,000$ exist such that $BE$ has integral length?
