comb_count_permutations_fixed_v1_1218484723_5741
A puzzle game has $n$ tiles labeled $1$ through $n$, where $n = \sum_{k_1=1}^{3} \varphi(k_1) \left\lfloor \frac{3}{k_1} \right\rfloor$. A valid configuration uses exactly $3$ fixed tiles and deranges the rest. The number of such configurations is $N = \binom{n}{3} D_{n-3}$. Compute the remainder when $37023N$ is divid...
