Pentacthularxitri (also called pentacthulto-pentacthulhum) is equal to E100#^^^#^^^#100 using Extended cascading-E notation.[1] The term was coined by Sbiis Saibian.

| Notation | Approximation |
|---|---|
| Bird's array notation | \(\{100,100[1[1 \lnot 3]1[1[1 \lnot 3]2 \lnot 2]2]2\}\) (Nested Hyper-nested Array Notation)
\(\{100,100[1[1 \backslash 2 \neg 2] 1 [1 [1 \backslash 2 \neg 2] 2 \neg 2] 2] 2\}\) (Hierarchial Hyper-nested Array Notation) |
| Fast-growing hierarchy | \(f_{\varphi(1,\Gamma_0,0)}(100)\) |
| Slow-growing hierarchy (using this system
of fundamental sequences) |
\(g_{\psi_0(\Omega_2^{\Omega_2+\psi_1(\Omega_2^{\Omega_2})})}(100)\) |
