Comment (by hthomas):
I've made a few more minor changes, mostly to the documentation, and also
catching that (T,(2,4,4)) = (E,7,1). I hope to be done #10527 soon!
I think the property "affine" should only be implemented for irreducible
quiver mutation types. It's not clear what it means for an reducible
quiver mutation type to be affine. (A product of two affines is, in my
view,
less affine than a product of an affine and a Dynkin is, since in the
latter case, but not the former, the radical of the symmetric form is
one-dimensional.)
I feel similarly about "elliptic" (though I have less mathematical
knowledge to back up my gut feeling that the product of two elliptics
isn't very elliptic).
Thoughts?
