Lines: 9 It remains to be shown that for a particular irrational number x, any positive integer n, and any sequence of digits of length n, there is a substring of the decimal representation of x which matches that sequence. Before trying a compression algorithm of the described kind, we should guarantee that the process of looking for the substring really terminates. --Juergen Wagner (gandalf@csli.stanford.edu) (wagner@iao.fhg.de)
