FGHs are used for assigning growth rates to fast computable functions, and are useful for approximating scores and halting times of Turing machines. == Definition == Given a system of fundamental sequences for limit ordinals below <math>\lambda</math>, its corresponding FGH is defined by <math display="block">\begin{array}{l} f_0(n) & = & n+1 \\ f_{\alpha+1..."
