An Equiquinoxal is 10(≡{≡}≡) using Dual Percoxy Notation.[1] This means that the base number subscript is an Equinoxal of Equinoxals. The term was coined by Matthew Tainsh in 2016.


The name of this number is based on Equinoxal and "qui", because the superscript is equal an Equinoxal of Equinoxals.
