Kiloenormatrixul is equal to Enormatrixul![200(2)200(2)200(2)200], using Hyperfactorial array notation. The term was coined by Lawrence Hollom.[1]

## Contents

### Etymology

The name of this number is based on SI prefix "kilo-" and the number "Enormatrixul".

### Approximations

Notation Approximation
Bird's array notation $$\{200,3,201[1[1\neg4]200[1\neg4]200[1\neg4]200]2\}$$
Hierarchical Hyper-Nested Array Notation $$\{200,3,201[1[1/3\sim2]200[1/3\sim2]200[1/3\sim2]200]2\}$$
BEAF $$\{200,3,201(\{X,\{X,\{X,199X,1,1,4\} \\ +199X,1,1,3\}+199X,1,1,2\})2\}$$[2]
Fast-growing hierarchy (using this system of FSes) $$f_{\varphi(1,0,0,\varphi(2,0,0,\varphi(3,0,0,198)+199)+199)+199}^2(200)$$
Hardy hierarchy $$H_{\varphi(1,0,0,\varphi(2,0,0,\varphi(3,0,0,198)+199)+199)\omega^{199}2}(200)$$
Slow-growing hierarchy $$g_{\theta(\varphi(1,0,0,\varphi(2,0,0,\varphi(3,0,0,\Omega+199)+199)+199)+199,} \\ _{\vartheta(\varphi(1,0,0,\varphi(2,0,0,\varphi(3,0,0,\Omega+199)+199)+199)+199))}(200)$$
