I lost an hour or so making sure I supplied the correct answer to today's mentalfloss.com Brain Game Tuesday Test Time puzzle, and I'm still not convinced of my success. Challenge me!

What is the largest integer that can
be spelled out in English using exactly
FOUR different letters of the alphabet?
(Each letter may be used multiple times.)

Here is the ANSWER.


FIFTY. This uses only the letters F, I, T, and Y.

Thanks for playing! Tomorrow, it's Wordplay Wednesday.
