Comment (by hthomas):

 Hi!

 I have some further mathematical corrections to !QuiverMutationType.

 Affine C is CC (not BC).

 D,n,2 is BB,n-1,1 (not CC,n,1).

 G,2,1 and G,2,-1 are reversed from what they should be.  (When this is
 fixed it will also fix D,4,3)

 For consistency, I think:
 * C,n,-1 should return the dual of C,n,1, i.e., BB (right now it gives an
 error).
 * B,n,-1 should return the dual of B,n,1, i.e., CD (ditto)

 I think I have now checked the data for affine types.

 I will go ahead and make these changes but I wanted to record them here in
 case anyone had any corrections to my corrections.

 cheers,

 Hugh
