User blog comment:Hyp cos/Analysis - BEAF, FGH and SGH (part 1)/@comment-5150073-20131024160701/@comment-11227630-20131025015941

Generally, (α1+α2+...+αm-1+αm)[n]=α1+α2+...+αm-1+(αm[n]) and we can only work on the last one. If the last one is ω, we can only work on the last ω.

But, in SGH we can change ω to n anywhere and it doesn't change the output of the function. So I say "the ω's in SGH are orderless".
