The primipenol is equal to \(s(3,2,6,2)\) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow2\rightarrow6\).

Etymology[]

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

Approximations[]

Notation Approximation
Bowers' Exploding Array Function \(\{3,27,4,2\}\)
Chained arrow notation \(3\rightarrow3\rightarrow2\rightarrow6\) (exact)
Hyper-E notation \(\textrm E2\#\#27\#26\#26\#26\#26\)
Hyperfactorial array notation \(26![5]\)
Fast-growing hierarchy \(f_{\omega+4}(26)\)
Hardy hierarchy \(H_{\omega^{\omega+4}}(26)\)
Slow-growing hierarchy \(g_{\varphi(1,3,0)}(27)\) (using this system of fundamental sequences)
