Counting all nine connected patterns

The Two Sides of Conditionals: Composite Antecedents and Consequents

The marginal note yields three same-type patterns plus three different-type pairs in two orders each.

Same-type:
1. Categorical / categorical
2. Connected / connected
3. Disjunctive / disjunctive
Mixed:
4. Categorical / connected
5. Connected / categorical
6. Categorical / disjunctive
7. Disjunctive / categorical
8. Connected / disjunctive
9. Disjunctive / connected

Thus 3 + (3 × 2) = 9. This counts internal component configurations, not modalities or quantifiers.
