This is follow-up to my earlier question.
Suppose that we have elements $\sigma_1,\ldots,\sigma_k\in S_n$, and that we established that these elements actually generate $S_n$. Since that previous question, I learned that the Bratus-Pak algorithm for recognising symmetric groups actually also produces a way to express every element of $S_n$ as a word in sigmas.
However, in some specific applications I have in mind (where $n$ is about 60), the transpositions $(i,j)$ in $S_n$ are thus expressed as words of length about 800 in sigmas, and I have strong reasons to suspect that there are much shorter ways to represent them (shorter than 100). Are there some methods that are known [in practice] to produce reasonably short words in the word group in such situation?
