A Short scale novemvigintillion or viginti-nonillion[1] is equal to \(10^{90}\).[2]

This number is also called triacontillion (not to be confused with Jonathan Bowers' one) in Greek-based naming system of zillions.[3]

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

Sbiis Saibian gave the name googolspeck,[4] referring to the value of this number.

In the Long scale a novemvigintillion is 10174 (the 29th power of a million) and 1090 is known as a quindecillion.
