Triahectillion

Triahectillion is equal to \(10^{3\times 10^{900}+3}\).Sbiis Saibian's large numbers site 1.8. Extensions to the -illions II: Jonathan Bowers' -illions
 The term was coined by Sbiis Saibian.
== Etymology ==
Tria- (in Latin) means three, and hect- (in Latin) means hundred. So triahectillion means the 300th tier 2 -illion.
