A permutation $\pi$ of $\{1, \dots, n\}$ can be represented in one-line notation as $\pi(1),\ldots,\pi(n)$. If all $n!$ permutations are written in lexicographic order then $\textrm{rank}(\pi)$ is the position of $\pi$ in this 1-based list.

For example, $\text{rank}(2,1,3) = 3$ because the six permutations of $\{1, 2, 3\}$ in lexicographic order are: $$1, 2, 3\quad 1, 3, 2 \quad 2, 1, 3 \quad 2, 3, 1 \quad 3, 1, 2 \quad 3, 2, 1$$

Let $Q(n)$ be the sum $\sum_{\pi}\sum_{i = 1}^{n!} \text{rank}(\pi^i)$, where $\pi$ ranges over all permutations of $\{1, \dots, n\}$.

For example, $Q(2) = 5$, $Q(3) = 88$, $Q(6) = 133103808$ and $Q(10) \equiv 468421536 \pmod {10^9 + 7}$.

Find $Q(10^6)$. Give your answer modulo $(10^9 + 7)$.
