An Equitrioxal is 10(≡≡≡) = 10(10(≡≡))(10(≡≡)) using Dual Percoxy Notation. This means that the number is equal to a power tower of Equiduoxal 10's with Equiduoxal at the top. The term was coined by Matthew Tainsh in 2016.
The name of this number is based on Equinoxal and "tri", because the superscript is equal to a triple Equinoxal.
