De Koninck–Doyon permutation-pattern conjecture
Establish, for every fixed integer \(k\ge 2\) and every permutation \((a_1,\ldots,a_k)\) of \((0,1,\ldots,k-1)\), that \(\#\{n\le x:P^+(n+a_1)<\cdots<P^+(n+a_k)\}\sim x/k!\) as \(x\to\infty\).

In 2011, De Koninck and Doyon [2] formulated a more general conjecture.
