Abstract
We build a bijection between the set of isomorphism classes of basic support -tilting modules over the Auslander algebra of and the symmetric group , which is an anti-isomorphism of partially ordered sets with respect to the generation order on and the left order on . This restricts to the bijection between the set of isomorphism classes of basic tilting -modules and the symmetric group due to Br\"{u}stle, Hille, Ringel and R\"{o}hrle. Regarding the preprojective algebra of Dynkin type as a factor algebra of , we show that the tensor functor induces a bijection between . This recover Mizuno's bijection for type .
