Query: An infinite family of higher-order difference operators that commute
  with Ruijsenaars operators of type $A$   We introduce a new infinite family of higher-order difference operators that
commute with the elliptic Ruijsenaars difference operators of type $A$. These
operators are related with Ruijsenaars' operators through a formula of Wronski
type.
