S(3,5,2,2)

Visualization of primitoltriplex using up-arrow notation

Primitoltriplex is equal to s(3,5,2,2) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow5\rightarrow2\). In up arrow notation it is equal to \(3\uparrow\uparrow\cdots\uparrow\uparrow3\) with primitolbiplex arrows.

Etymology[]

The name of this number is based on the prefix "tri-" and the number "primitolplex".
