This function is as strong as Dropping array notation (a part of Strong array notation), or R function, when it is defined, and corresponds to the strength of both in the FGH.

The EFGH is discontinous and has gaps at limit ordinals, so it is nowhere in the EFGH (Technally, it corresponds to A[n], where n is the strength in the FGH). To remove the gaps in the EFGH, change the limit rule to simply H_a(n) = H_a[n](n). If we do that, it will catch up with the FGH at w^w and all multiples of it, so it will correspond to the same ordinal.

I commented the same thing when I was logged out, sorry!
