- It is an old result of Stanley that the number of reduced words for the longest permutation in Sn is the dimension of the irreducible representation of the symmetric group indexed by the staircase shape partition $\delta_=(n−1,n−2,…,2,1)$
- Involution words are certain analogues of reduced words for involutions in Coxeter groups, first studied under the name of "admissible sequences" by Richardson and Springer.
