Fugasix

Fugasix is equal to 665, or \(6 \downarrow \downarrow 6\) using down-arrow notation. The name is formed by applying the fuga- prefix to 6. It has exactly 6,051 digits, meaning that it's larger than a googolbell but smaller than a googoltoll. In the Misalian seximal system, this number is called "untrinilnilnilexian".
