Leetcode 2741. Special Permutations

Count the number of permutations of distinct positive integers where every adjacent pair satisfies that one divides the other, returning the result modulo 10^9+7. With n ≤ 14 this is typically solved by treating divisibility as edges in a graph and using bitmask DP to count Hamiltonian paths.
