Apart from million, the words in this list ending with -illion are all derived by adding prefixes (bi-, tri-, etc., derived from Latin) to the stem -illion. Centillion appears to be the highest name ending in -"illion" that is included in these dictionaries. Trigintillion, often cited as a word in discussions of names of large numbers, is not included in any of them, nor are any of the names that can easily be created by extending the naming pattern (unvigintillion, duovigintillion, duoquinquagintillion, etc.).
All of the dictionaries included googol and googolplex, generally crediting it to the Kasner and Newman book and to Kasner's nephew. None include any higher names in the googol family (googolduplex, etc.). The Oxford English Dictionary comments that googol and googolplex are "not in formal mathematical use".

Famous quotes containing the words standard, dictionary and/or numbers:
“We don’t want bores in the theatre. We don’t want standardised acting, standard actors with standard-shaped legs. Acting needs everybody, cripples, dwarfs and people with noses so long. Give us something that is different.”
—Dame Sybil Thorndike (1882–1976)
“I am hungry and you give me
a dictionary to decipher.”
—Anne Sexton (1928–1974)
“Old age equalizes—we are aware that what is happening to us has happened to untold numbers from the beginning of time. When we are young we act as if we were the first young people in the world.”
—Eric Hoffer (1902–1983)
