Superior Grand Megaenourmabixul is equal to ((...((200![200(2)200(2)200,200])![200(2)200(2)200,200])...)![200(2)200(2)200,200])![200(2)200(2)200,200] (with Superior Megaenourmabixul parentheses), using Hyperfactorial array notation. The term was coined by Lawrence Hollom.[1]

## Contents

### Etymology

The name of this number is based on the word "superior" and the number "Grand Megaenormabixul".

### Approximations

Notation Approximation
Bird's array notation $$\{200,\{200,4,201[1[1\neg4]200[1\neg4]200,200]2\} \\ ,201[1[1\neg4]200[1\neg4]200,200]2\}$$
Hierarchical Hyper-Nested Array Notation $$\{200,\{200,4,201[1[1/3\sim2]200[1/3\sim2]200,200]2\} \\ ,201[1[1/3\sim2]200[1/3\sim2]200,200]2\}$$
BEAF $$\{200,\{200,4,201(\{X,\{X,199X^2+199X,1,1,3\}+199X,1,1,2\})2\} \\ ,201(\{X,\{X,199X^2+199X,1,1,3\}+199X,1,1,2\})2\}$$[2]
Fast-growing hierarchy (using this system of FSes) $$f_{\varphi(1,0,0,\varphi(2,0,0,\omega199+199)+199)+200}(f_{\varphi(1,0,0,\varphi(2,0,0,\omega199+199)+199)+199}^3(200))$$
Hardy hierarchy $$H_{\varphi(1,0,0,\varphi(2,0,0,\omega199+199)+199)\omega^{200}+\varphi(1,0,0,\varphi(2,0,0,\omega199+199)+199)\omega^{199}3}(200)$$
Slow-growing hierarchy $$g_{\theta(\varphi(1,0,0,\varphi(2,0,0,\Omega200+199)+199)+200,\vartheta(\varphi(1,0,0,\varphi(2,0,0,\Omega200+199)+199)+200))}(3)$$
