The geegolplex is equal to {10,geegol,4} in BEAF.[1] The term was coined by Jonathan Bowers. In the up-arrow notation it can be written as \(10 \uparrow\uparrow\uparrow\uparrow \text{geegol}\).
Geegolplex is equal to E1#1#1#100#2 = E1#1#1#100#(E1#1#1#100) = E1#1#1#geegol in Hyper-E notation.
Aarex Tiaokhiao calls this number geegolquadrex.[2]
Etymology[]
The name of the number is based on suffix -plex and the number geegol.
Approximations[]
| Notation | Approximation |
|---|---|
| Hyper-E notation | \(\textrm{E}1\#1\#1\#100\#2\) (exact) |
| Chained arrow notation | \(10 \rightarrow (10 \rightarrow 100 \rightarrow 4) \rightarrow 4\) (exact) |
| Hyperfactorial array notation | \((102!3)!3\) |
| Fast-growing hierarchy | \(f_5(f_5(100))\) |
| Hardy hierarchy | \(H_{(\omega^5) 2}(100)\) |
| Slow-growing hierarchy | \(g_{\eta_{\eta_0}}(100)\) |
