COMMENTS
There are 107 terms, considering all terms up to 10^66 using English names of large numbers and various conventional extensions thereof (see Wikipedia link), since quadrillion, quintillion, etc. each have three or more syllables themselves. Terms like "one googol" (or possibly "a googol"), "two googol," ..., "twelve googol" are unconventional, hence disallowed. - Michael S. Branicky, May 28 2024
