| Notation | Approximation |
|---|---|
| Bowers' Exploding Array Function | X↑↑↑90 & 100 |
| Bird's array notation | {100,90[1[1¬3]2]2} |
| Fast-growing hierarchy | \(f_{\varphi(1,0,0)[90]}(100)\) (using this system of fundamental sequences) \(=f_{\Gamma_0[90]}(100)\) |
| Hardy hierarchy | \(H_{\varphi(1,0,0)[90]}(100)\) (using this system of fundamental sequences) \(=H_{\Gamma_0[90]}(100)\) |
