| Notation | Approximation |
|---|---|
| BEAF | \(\{X,X,1,2\}\ \&\ 1000\) (weaker bound)
\(\{X,X,3\}\ \&\ 1000 \) (stronger bound) |
| Bird's array notation | \(\{100,1000[1[1\neg3]2]2\}\) |
| Hyperfactorial array notation | \(1000![1(1)2]\) |
| Dollar function | \(1000$[[[[0]_2]_2]_2]\) |
| Fast-growing hierarchy (with this system of fundamental sequences) | \(f_{\varphi(1,0,0)}(999)\) \(=f\)\(_{\Gamma_0}\)\((999)\) |
| Hardy hierarchy (with this system of fundamental sequences) | \(H_{\Gamma_{0}}(1000)\) |
