摘要：

This is the third in a series of papers which give an explicit description of the reconstruction algebra as a quiver with relations; these algebras arise naturally as geometric generalizations of preprojective algebras of extended Dynkin quivers. This paper is the companion to [W12] and deals with dihedral groups G = D-n,D-q which have rank two special CM modules. We show that such reconstruction algebras are described by combining a preprojective algebra of type (D) over tilde with some reconstruction algebra of type A.
