A quinvigintillion is equal to \(10^{78}\) in the short scale, or \(10^{150}\) in the long scale by Conway and Guy's naming system[1][2][3] or by Rowlett's naming system.[4]
In the long scale, 1078 is called tredecillion, which is commonly used in France and Germany.
Sbiis Saibian gave the name viginti-quintillion referring to the value of this number.[5]
