Tethrinooteron

Tethrinooteron is equal to \(\{100,100[1\backslash1\backslash1\backslash1\backslash2]2\}\) in Bird's array notation, using the modified Hierarchical Hyper-Nested Array Notation.Hayden's Big Numbers - My BAN and SAN numbers Retrieved 2023-05-25. The term was coined by googology user HaydenTheGoogologist2009.
