Extritri

Extritri is equal to 3(1#1#1, 3)3 = 3(1##3, 3)3 in Hayden's Array Notation. The term was coined by googology user HaydenTheGoogologist2009.Hayden's Big Numbers. Retrieved 2022-05-11. It is ill-defined, as we explain in #Issues section.
== Issues ==
Another user pointed out that there is no rule applicable to solve 3(1#1#1, 3)3 in Hayden's Array Notation,A difference page of a talk page. although this number is intended to be solved by the rule a(1#1#1, 1)b = a(1##3, 1)b = {a, b (((1)1)1) 2}A difference page of a talk page. and to be a power of \(3\) of iterated Cantor normal form levelA difference page of this article, Since the expression is not a valid expression in Hayden's Array Notation, it is ill-defined and hence its size is not determined.
== Approximations ==
Since it is ill-defined, we give an approximation of an intended value.
