Description
The number of permutations whose descent word is the given binary word.
This is the sizes of the preimages of the map Mp00109descent word.
This is the sizes of the preimages of the map Mp00109descent word.
Map
descent word
Description
The descent positions of a permutation as a binary word.
For a permutation $\pi$ of $n$ letters and each $1\leq i\leq n-1$ such that $\pi(i) > \pi(i+1)$ we set $w_i=1$, otherwise $w_i=0$.
Thus, the length of the word is one less the size of the permutation. In particular, the descent word is undefined for the empty permutation.
