Not to be confused with googolplex.

The goggolplex is equal to {10,goggol,6} in BEAF.[1] The term was coined by Jonathan Bowers. In up-arrow notation, it can be written as $$10 \uparrow^6 \text{goggol}$$.

Aarex Tiaokhiao calls this number goggolhex.[2]

## Etymology

The name of the number is based on suffix -plex and the number goggol.

## Approximations

Notation Approximation
Hyper-E notation $$\textrm E1\#1\#1\#1\#1\#(\textrm E1\#1\#1\#1\#100)$$ (exact)
Chained arrow notation $$10 \rightarrow (10 \rightarrow 100 \rightarrow 6) \rightarrow 6$$ (exact)
Hyperfactorial array notation $$(102!5)!5$$
Fast-growing hierarchy $$f_7(f_7(100))$$
Hardy hierarchy $$H_{(\omega^7) 2}(100)$$
Slow-growing hierarchy $$g_{\varphi(5,\varphi(5,0))}(100)$$
