There are three special patterns formed by a pair of ELS's:
parallel, collinear,
and perpendicular. The fourth, general case, is diagonal - the most common.
The pattern names refer to how these ELS's look
in a table; brief descriptions of these patterns are
here.
It may be that a large number of ELS's found in special patterns
(non-diagonal) are intentionally encoded. In any case, they are a
smaller set and therefore easier to study and measure significance.
Initial results have yielded several dramatically non-random examples of
such patterns in the Torah.
Interesting pictures and results for the three rare patterns follow:
Any of these three studies, by itself,
strongly demonstrates the codes thesis.
More precise quantification is not possible until many more
control runs are completed and compared.
