Ecetontridex is equal to E303#1#4 = E303#(E303#1#3) = EE...EE303 (ecetondudex E's) = 101010...1010303 (ecetondudex 10's), using Hyper-E Notation.[1] The term was coined by Sbiis Saibian. This number belongs to the grangol regiment.

## Approximations

Notation Approximation
Arrow notation $$10 \uparrow\uparrow 10 \uparrow\uparrow 10 \uparrow\uparrow 10^{303}$$
Chained arrow notation $$10 \rightarrow (10 \rightarrow (10 \rightarrow (10 \rightarrow 303)) \rightarrow 2) \rightarrow 2$$
BEAF $$\{10,\{10,\{10,\{10,303\},2\},2\},2\}$$
Fast-growing hierarchy $$f_3^3(f_2(997))$$
Hardy hierarchy $$H_{\omega^3 3+\omega^2}(997)$$
Slow-growing hierarchy $$g_{\varepsilon_{\varepsilon_{\varepsilon_{\omega^{\omega}}}}}(303)$$
