We extend Friedman's theorem to show that, for any fixed $r$, the random $2r$--regular Schreier graphs depicting the action of $r$ random permutations of $[n]$ on $k_{n}$--tuples of distinct elements in $[n]$ are a.a.s. weakly Ramanujan, for any $k_{

Schur--Weyl--Jones duality establishes the connection between the commuting actions of the symmetric group $S_{n}$ and the partition algebra $P_{k}(n)$ on the tensor space $\left(\mathbb{C}^n\right)^{\otimes k}.$ We give a refinement of this, determi
