Let k be an algebraically closed field and G a finite nontrivial group whose order is not divisible by the characteristic of k. Associated with an m-dimensional representation of G is the McKay quiver, whose vertices correspond to the irreducible representations of G. We show that if m = 2, then the underlying graph of the separated McKay quiver is a finite union of extended Dynkin diagrams.
