OBSERVATIONS:
- Interesting... So the columns repeat after 4 columns. Which means columns
1, 5, 9, etc. have the same values. In general, if there i rows and j
columns, then j, i+j, 2i+j, ... have the same column compositions.
- Some nodes are two-way; that is, they are inverses of each other. Most nodes
are one-way as expected of One-Way Woods.
