Sprach Zarathustra

Sprach Zarathustra is one of the biggest googolisms ever defined by Sbiis Saibian, being equal to E100{#&#&#&#&#&#&.........#&#&#&#&#}100 with 100 #'s = E100{#,#/2}100.
== Etymology ==
The name is most likely a reference to 's famous composition Also Sprach Zarathustra, a piece cast into public recognition by the fact it was used as the theme for . As much of Saibian's website contains imagery from the movie, it is likely Saibian coined this number with that in mind.
==Approximations==
Since it is not defined by now, the following approximation is just an expected value.
Notation 	Approximation
Bowers' Exploding Array Function	\(\lbrace100,101/2\rbrace\)
Bird's array notation 	\(\lbrace100,101[1\bullet2]2\rbrace\)
Fast-growing hierarchy (using this system
of fundamental sequences)	\(f\)\(_{\psi_0(\Omega_{\omega})}\)\((100)\)
Hardy hierarchy 	\(H_{\psi_0(\Omega_{\omega})}(100)\)
Slow-growing hierarchy 	\(g_{\psi_0(\Omega_{\omega})}(100)\)
