Editing Final Report 2010 (section)

====Discussion====
The results, for each pattern possibility, have been tabulated and can be found in the appendix. A few example results tables are shown below.  The highlighted cells depict the patterns that are an exact match to the pattern sourced from the mystery code.

The first thing that is apparent from the results is the similarities between the different types of text.  This suggests that the general occurrence of the order of initial letters in English is independent of the source.  That is, it does not really matter where the raw text is from as it is all English and will produce very similar results.


The second interesting point is the highlighted results that relate to the letters taken directly from the mystery code.  Having these results occur in the top list of results implies that it is still technically possible that the code is in fact an initialism without substitution. However, apart from the patterns of one letter (@@@@ and @@@), there is a very large spread of results with the top result usually only about 5% of the total amount of matches found.  The top 26 matches are shown for each search however in the full list some patterns returned results with up to 500 different match variations.  This suggests that it is highly likely that if the mystery code is in fact initialism, there is a good chance that it is also using some type of substitution method.  That is, each letter is actually representing a different letter.


The very low amounts of matches found that are a direct link from the book of Rubaiyat and the mystery code is also important.  This book, linked so closely to the murder, would be the most obvious source of the code.  It is clear from the results that if the code has been made as an initialism from the Rubaiyat then it is definitely also incorporating substitution.
