On the cycle structure of the product of random maximal cycles
  The subject of this paper is the cycle structure of the random permutation $\sigma$ of $[N]$, which is the product of $k$ independent random cycles of maximal length $N$. We use the character-based Fourier transform to study the number of cycles of $\sigma$ and also the distribution of the elements of the subset $[\ell]$ among the cycles of $\sigma$.
