In Ross Eckler's new book "Making the Alphabet Dance", he answers the question:
"If the numbers between one and one thousand vigintillion minus one are arranged in alphabetical order instead of numerical order, is there any number name in the list that matches its position in the numerical list?"
His answer is no.
The first number is eight.
The last number is two vigintillion two undecillion two trillion two thousand two hundred two.
The first prime number is eight billion eighteen million eighteen thousand eight hundred fifty one.
The last prime number is two vigintillion two undecillion two trillion two thousand two hundred ninety three.
I recommend this book to all wordplay lovers. It has a mathematical flavor.
