> it was really confusing to put letters with a notation that uses letters But did you understand? If so, can you tell me your rate of growth?

I could not fully understand the meanings of \(f_{a+x}(n)\) and \(f_n^x(n)\). As you said that \(f_1(0)\) is computed by the usual FGH, \(f_n^x(n)\) would be the one in FGH. It is ok now. So what does \(f_{a+x}(n)\) mean? It is just a notation with letters and numbers? Or do you intend some computation of \(a+1\)? I guess that this is just a notation.
