Tethritertope is equal to E100#^^(#^#)>#100 in Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian. This number belongs to the tethratope regiment.
Approximations[]
| Notation | Approximation |
|---|---|
| BEAF | \(\{X,X^2,X\}\ \&\ 100\) (Non-climbing)
\(X \uparrow\uparrow (X^X+1)\ \&\ 100\) (Climbing) |
| Bird's array notation | \(\{100,100[1[2\neg2]1,2]2\}\) |
| Fast-growing hierarchy | \(f_{\varphi(\omega,\omega)}(100)\) |
| Hardy hierarchy | \(H_{\varphi(\omega,\omega)}(101)\) |
| Slow-growing hierarchy (Using this system of fundamental sequences) | \(g_{\psi_0(\Omega_2^\Omega\omega)}(100)\) |
