Are there numbers that can’t be said?
My first answer was: “yes, a number with so many digits in a given base that a whole life can’t be enough to say it”.
I started trying to find an answer to this question thinking back to the old short story “The Nine Billion Names of God” written by Arthur C. Clarke.
Do you know another element of that set of numbers? A not trivial example would be appreciated.

Well… of course… there is the (in)famous 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56
it’s the patented number that can’t be said ’cause it’s copyrighted by HD-DVD producers and it can crack HD-DVD
ssshh…you can’t say to anyone ok?
<p>Even though the number that you suggest is not lethal, it is a correct answer to my question! :)</p>
