For English we extract the next 104009 letters from Dr Thorndyke Short Story Omnibus.

We count the χ-values of 2000 pairs of 26 letter chunks and use a spreadsheet.

The figure and table show some characteristics of the distribution.

To get χ-values divide x-values in the graphic by 26 x 26 = 676.
