Paired N-Grams

The enneagram is a paired N-Gram, made of two atomic N-Grams which together touch every point of the circle once. The top point of the circle is the only point touched more than once, as it is part of every atomic N-Gram. In the table organized by base, you will find paired N-Grams in each row, equidistant from the vertical line drawn down the center of the table. Here is a variation on this table, "folded" along this line, with the figures from the right-hand side drawn in red.
