The duonanillion is equal to 106,000,000,003 in short scale.[1] It is equal to 1012,000,000,000 in the long scale. It is defined using Sbiis Saibian's generalization of Jonathan Bowers' -illion system. It is equal to 1 followed by 6,000,000,003 zeros. It is 6,000,000,004 digits long.
Duonanillion is also known as "one duomilliamilliamilliatillion" according to Landon Curt Noll's The English name of a number.
