Abstract

We prove the exact asymptotic 1(2π3827288π+o(1))/n1-\left({\frac{2\pi}{3}-\frac{827}{288\pi}}+o(1)\right)/{\sqrt{n}} for the probability that the underlying graph of a random mapping of nn elements possesses a unique highest tree. The property of having a unique highest tree turned out to be crucial in the solution of the famous Road Coloring Problem as well as the generalization of this property in the proof of the author's result about the probability of being synchronizable for a random automaton.
