  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  countable 
 
    A  term  describing  a  {set}  which  is  {isomorphic} 
  to  a  subet  of  the  {natural  numbers}.  A  countable  set  has 
  "countably  many"  elements.  If  the  isomorphism  is  stated 
  explicitly  then  the  set  is  called  "a  counted  set"  or  "an 
  {enumeration}". 
 
  Examples  of  countable  sets  are  any  {finite}  set  the  {natural 
  numbers},  {integers},  and  {rational  numbers}.  The  {real 
  numbers}  and  {complex  numbers}  are  not  [proof?].
