On Baxter's Q operator of the higher spin XXZ chain at the
Razumov-Stroganov point    [PDF]

Based on the conjecture for the exact eigenvalue of the transfer matrix of the higher half-integer spin XXZ chain at the Razumov-Stroganov point, we evaluate the corresponding Baxter's Q operator in closed form by solving the TQ equation. The combination of the Q operators on the "right side" and the "wrong side" is shown to produce the hierarchy of functional relations. The functional relations and the explicit forms of the Q operators lead to various combinatorial identities.
