Gargantuan

Gargantuan is equal to {10, 10 / 10} = {10 & 10 & 10 & 10 & 10 & 10 & 10 & 10 & 10 & 10 / 9} in BEAF. The term was coined by googology user HaydenTheGoogologist2009.Hayden's Big Numbers. Retrieved 2022-08-11. Since BEAF is unformalised at this level, it is ill-defined. The number is named after the sandwich sold by Jimmy John's.
== Approximations ==
Since it is not defined by now, the following approximations are just expected values:
Notation 	Approximation
Bird's array notation 	\(\{10, 10 [1 [2 /_{1,2} 2] 2] 10\}\) (debatable)
DeepLineMadom's Array Notation	\(10[1\{1\backslash 1,2\}10]10\) (debatable)
Fast-growing hierarchy (using this system
of fundamental sequences)	\(f_{\psi_0(\Omega_{\omega})\omega}(10) = f_{\psi_0(\Omega_{\omega}+1)}(10)\) (debatable)
