Yes. The set of negative integers, for example; or the set of reals 
between 0 and 1.

(Yeah, hi. I'm around, but mostly here, on sci.crypt, and on 
rec.puzzles, all three of which are low-traffic - or low-signal, anyway. 
I stopped bothering with clc when it started morphing into a religious 
debating forum. I haven't been back to check whether that trend continued.)
