Bijections and symmetries for the factorizations of the long cycle

Olivier Bernardi, Alejandro H. Morales

We study the factorizations of the permutation $(1, 2, ..., n)$ into $k$ factors of given cycle types. Using representation theory, Jackson obtained for each $k$ an elegant formula fo…

Direct bijective computation of the generating series for 2 and 3-connection coefficients of the symmetric group

Alejandro H. Morales, Ekaterina A. Vassilieva

We evaluate combinatorially certain connection coefficients of the symmetric group that count the number of factorizations of a long cycle as a product of three permutations. Such…
