@Simplicity:

"My FGH rules do not imply only Knuth arrows as Deedlit11 said'"

I think you misunderstood my comment - I was responding to Denis's comment that the normal FGH had a problem because its values cannot be easily expressed in terms of Knuth arrows. I was just saying I don't see that as a problem - in fact, one could just as easily say that Knuth arrows have the problem, since their values cannot be easily expressed in terms of FGH!

I'm pretty sure LittlePeng9 is fully aware that the FGH can be defined in many ways; he was just saying that, to him, _the_ FGH refers to the most common definition of FGH. (the n+1 version)

@Denis:

Actually, your version is not a different variant of FGH, since $$f_\alpha^a(1) = f_\alpha^{a-1}(10)$$.
