Tethexo

View full site to see MathJax equation

Tethexo is equal to s(4,4,6) in strong array notation. The term was coined by wiki user Hyp cos. It can be represented in up-arrow notation as \(4\uparrow\uparrow\uparrow\uparrow\uparrow\uparrow4\) (4 octated to 4).

This number is also equal to s(4,2,7) and s(4,6,1,2).

Etymology

The name of this number is based on the word "tetra" and "hexa" (Greek for 4 and 6), meaning a base-4 number, generated using hyper-6 operation based on exponentiation.
