Yersohotillion is equal to 103*103*102.4*1040+ 3*103*10300+ 3. The term was coined by Trakaplex trying to make puns on Bowers' illions on answers.com.  This was the first confirmed quantity, though the name itself was first mentioned on a jocular Googology Testing wiki post trying to use illions as examples in sentences.
It comes from 'yersillion' and 'hotillion' with an "o" vowel first introduced in Tier 2.
