Octodecillion

An octodecillion or nonilliard^[1] is equal to 10⁵⁷ in America, or 10¹⁰⁸ in France and Germany.^[2][3]

In the long scale, 10⁵⁷ is called nonilliard, which is commonly used in France and Germany.

This number is also called enneadekillion in Russ Rowlett's Greek-based naming system.^[4]

Donald Knuth calls this number enneciad, and it's equal to using the -yllion system.
