User blog comment:Hyp cos/Analysis - BEAF, FGH and SGH (part 2)/@comment-5529393-20131030064827

The problem for me is that Bowers' notations are so ambiguous after Extended Array Notation. So if you take your guiding principle to be that the & operator maps the SGH to the FGH, there's nothing on Bowers' page to contradict it. But you could take a different guiding principle and get totally different evaluations.

For example, there's no evidence that 3 & 3 & 3 & 3 means X1 & X2 & X3 & 3 where the Xi are all different.
