Just pointing out, writing  ω ω ω. . ..C(0)+1     for what I believe you mean is an abuse of notation. There is no "top" of this stack. The only really good way to express this is to simply write that this number is a limit of \(C(0)+1,\omega^{C(0)+1},\omega^{ \omega^{C(0)+1}},...\).

Also, what FS's do you use?
