Visualization of primitoltquadriplex using up-arrow notation

Primitolquadriplex is equal to s(3,6,2,2) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow6\rightarrow2\). In up arrow notation it is equal to \(3\uparrow\uparrow\cdots\uparrow\uparrow3\) with primitoltriplex arrows.

Etymology

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