Quadruple Whopper

Quadruple Whopper or tetrahectakulus is equal to \(\underbrace{400\ \&\ 400\ \&\ 400 \cdots 400\ \&\ 400\ \&\ 400}_{\text{400 400's}} = \{400,400/2\}\) using BEAF. This term was coined by XRQ CORPORATION.XRQ CORPORATION's Golapulus Series Accessed 2022-10-06. The array of operator is unformalized at this level.
==Approximations==
Since it is not defined by now, the following approximations are just expected values:
Notation 	Approximation
Bird's array notation	\(\{400,400 [1 [1 /_{398} 1,2 /_{399} 2]_1 2] 2\}\)
Fast-growing hierarchy (using this system
of fundamental sequences)	\(f_{\psi_0(\Omega_\omega)}(400)\)
