Question 85

Inside a circle of radius $1$ (or on the circumference), one marks $n$ points in such a way that the minimal distance between two marked points is as large as possible. Let $d_n$ be this distance between the two closest points. Is it true that $d_{n+1} \lt d_n$ for every natural number $n \ge 2$?
