(ii) the set of possible limits is dense in $[0,1]$. Our tools come mainly from analytic combinatorics and singularity analysis. [3/3 of https://t.co/AEBt88kJz8]

permutation of size $n$ satisfies $\Psi$ admits a limit as $n$ is large. Moreover, we establish two further results about the behaviour and value of $p_{n,\Psi}$: (i) it is either bounded away from $0$, or decays exponentially fast; [2/3 of https://t.co…
