Ralf,

On those two, at least, the two of us agree. :-)
But, for me, the list of "special" numbers would have to extend beyond Zero
and One; for starters, I'd have to include Two. As numbers (here in the
sense of "positive integers") go, I'd say it's special in several ways!
E.g.,
- smallest number that can be used as the base of a positional numeral
system
- smallest prime number
- smallest number whose square root is irrational
- only factorial that is also prime
- largest number that is its own factorial

Thanks for writing,
