user: After moving his sticky toy spider one morning, Tony heads outside to play "pirates" with his pal Nick, who lives a few doors down the street from the Kubiks. Tony and Nick imagine themselves as pirates in a rough skirmish over a chest of gold. Victorious over their foes, Tony and Nick claim the prize.

user: A permutation of a finite set is a one-to-one function from the set onto itself. A cycle in a permutation $P$ is a nonempty sequence of distinct items $x_1, \ldots, x_n$ such that $P(x_1) = x_2$, $P(x_2) = x_3$, $\ldots$, $P(x_n) = x_1$.

Every permutation of a finite set splits the set into a finite number of disjoint cycles. If this number equals 2, then the permutation is called bi-cyclic. Compute the number of bi-cyclic permutations of the 7-element set formed by the letters of "PROBLEM".
