A duodecillion is equal to 1039 in America, or 1072 in France and Germany.[1]

In the long scale, 1039 is called sextilliard, which is commonly used in France and Germany.

This number is also called trisdekillion in Russ Rowlett's Greek-based naming system,[2] and doedecillion by Jonathan Bowers.[3]

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