McKay correspondence[edit]

I believe that something like the following is true:

The irreducible representations of the binary polyhedral groups correspond to the nodes of the associated ADE Dynkin diagram,
and the dimension of the representation are the labels discussed in Proctor.

I’m pretty sure these labels are some form of dimension of a representation, as indicated in (Proctor 1993), but he doesn’t elaborate, and I can’t find references that do, so for now I’ll leave this on the talk page.

Any (referenced) elaboration would be much appreciated!
