A sesvigintillion or sevigintillion is equal to \(10^{81}\) in the short scale, or \(10^{156}\) in the long scale. Sesvigintillion is a name based on Conway and Guy's naming system,[1][2][3][4] and sexvigintillion is a name based on Russ Rowlett's naming system.[5]
In the long scale, \(10^{81}\) is called tredecilliard, which is commonly used in France and Germany.
