As LittlePeng said, there are some undefined moments in your notation. Nevertheless 3-entry array must work being expressed via FGH (Wainer hierarchy) $$(a,b,c)=f_{\omega a+b}(c)$$. What about 3-entry array we should use imagination to understand what do you mean. Fixed points of $$\alpha\rightarrow \omega+\alpha}(c)$$ are exponents of omega. Fixed points of $$\alpha\rightarrow \omega^\alpha}(c)$$ are epsilon numbers. Unclear what do you mean.
