Tethrinoocrossmax

is equal to \(\{100,100[1[2\backslash_{1[1\backslash1\backslash2]2}2]2]2\}\) in Bird's array notation, using the modified Hierarchical Hyper-Nested Array Notation. The term was coined by googology user .
== Etymology ==
"" is based on Tethrinoocross and "-max" indicating the Tethrinoocross array at the ultraseparator.
