Tetenhex is equal to s(6,6,6,6) in strong array notation.[1] It can be represented in chained arrow notation as \(6\rightarrow6\rightarrow6\rightarrow6\rightarrow6\rightarrow6\rightarrow6\rightarrow6\).

This number is also equal to s(6,6,1,7), s(6,1,1,8), s(6,6,1,1,2), s(6,1,1,2,2), or s(6,1,1,1,1,2).

Etymology[]

The name of this number is based on Greek prefixes tetra- and hexa- (four and six), meaning that there are 4 6's in the array.
