the extent of generalization

[andydude]

It sounds to me like you refer to i-tetra-i, or \( {}^{i}i \). in your notation, I think you mean \( (a, b, c) = \exp^c_a(b) \) which would actually make \( (i, i, i) = \exp^i_i(i) = \exp^{i+1}_i(1) = {}^{i+1}i \) which is probably not what you were trying to say.

I have never tried to calculate i-tetra-i before. All of the bases that I've tried have been real-valued, but I'll see what I can do for a complex base. I cannot guarantee any results, but I can see what our methods can do for base i.
