	* Frequency analysis of the numbers was similarly unsuccessful. Assuming the string was one-digit numbers gave far too much repetition of characters (for example the 484848 would probably be tetete or etetet) for a meaningful message. Assuming the string was 2 (or more) digit numbers prevented frequency analysis simply because there wasn't enough data to work with (frequency analysis works best over a very large amount of encrpyted data).		* Frequency analysis of the numbers was similarly unsuccessful.
