Gaskets by Forbidden Triples

To produce a picture of four gaskets using forbidden pairs, we forbid 1 → 1, 1 → 2, 1 → 3, and 1 → 4.

To achieve these with forbidden triples, we forbid all of the form i → 1 → j.

From the software description, we see that to forbid all triples i → 1 → j, we set to 0 all entries in the first column.
