Heptalogialogue in zeroes

The heptalogialogue is equal to E1#7#2 using Hyper-E notation.[1] The term was coined by Sbiis Saibian. In arrow notation, this number is equal to $$10↑↑10↑↑7$$.

## Etymology Edit

The 2 parts of the name, ''heptalogia'' and ''logue'' means Heptalogue and $$10↑↑\text{n}$$, which formed $$10↑↑10↑↑7$$ when concentrated from left to right. So the full name indicates the ordinal index of the number.

## Approximations in other notations Edit

BEAF $$\{10,\{10,7,2\},2\}$$ (exact)
Hyperfactorial array notation $$((((((13!)!)!)!)!)!)!1$$
Fast-growing hierarchy $$f_3(f_2^6(28))$$
Hardy hierarchy $$H_{\omega^3+(\omega^2) 6}(28)$$
Slow-growing hierarchy $$g_{\epsilon_{\omega^{\omega^{\omega^{\omega^{\omega^{\omega^{\omega}}}}}}}}(10)$$
