Query: On Expected Factors in Reduced Decompositions in Type B   The expected number of Yang-Baxter moves appearing in a reduced decomposition
of the longest element of the Coxeter group of type B_n is computed to be
2-4/n. For the same element, the expected number of 0101 or 1010 factors
appearing in a reduced decomposition is 2/(n^2-2).
