Summary: | We introduce a new class of permutations, called web permutations. Using these permutations, we provide a combinatorial interpretation for entries of the transition matrix between the Specht and
$\operatorname {SL}_2$
-web bases of the irreducible
$ \mathfrak {S}_{2n} $
-representation indexed by
$ (n,n) $
, which answers Rhoades’s question. Furthermore, we study enumerative properties of these permutations. |
