McKay graph
text:
In mathematics, the McKay graph of a finite-dimensional representation V of a finite group G is a weighted quiver encoding the structure of the representation theory of G. Each node represents an irreducible representation of G. If χ i, χ j are irreducible representations of G, then there is an arrow from χ i to χ j if and only if χ j is a constituent of the tensor product V ⊗ χ i . Then the weight nij of the arrow is the number of times this constituent appears in V ⊗ χ i . For finite subgroups
