Duodecillion

A duodecillion is equal to 1039 in America, or 1072 in France and Germany. In his novel Postsingular, Rudy Rucker jokingly used the term umptisqiuddlyzillion to refer to the American value of this number. 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, and doedecillion by Jonathan Bowers. Aarex Tiaokhiao gave the name trecillion, referring to the value of this number.
