The primitol is equal to s(3,2,2,2) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow2\rightarrow2\). In up arrow notation it is equal to \(3\uparrow\uparrow\cdots\uparrow\uparrow3\) with 27 arrows.

EtymologyEdit

The name of this number is based on the word "primitive", meaning the top of primitive recursive arithmetic.
