Visualization of primitetol using up-arrow notation

Primitetol is equal to s(3,2,5,2) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow2\rightarrow5\).

Etymology

The name of this number is based on the prefix "tetra-" and the number "primitol".

Approximations

Notation Approximation
BEAF \(\{3,27,3,2\}\)
Hyper-E notation \(\textrm E2\#\#27\#26\#26\#26\)
Chained arrow notation \(3\rightarrow3\rightarrow2\rightarrow5\) (exact)
Hyperfactorial array notation \(26![4]\)
Fast-growing hierarchy \(f_{\omega+3}(26)\)
Hardy hierarchy \(H_{\omega^{\omega+3}}(26)\)
Slow-growing hierarchy \(g_{\varphi(1,2,0)}(27)\) (using this system of fundamental sequences)
