Original question and givens

Use the full fixed carrier Fin(6)={0,…,5} and complete distinct ordered relation pairs=[[0, 0], [1, 1], [2, 2], [3, 3], [4, 4], [5, 5], [0, 1], [0, 2], [0, 3], [0, 4], [1, 0], [3, 0]]. Check reflexivity, symmetry and transitivity separately on the whole carrier. Equivalence classes may be emitted only after all three qualifications pass; one counterexample refutes its corresponding axiom. Give (n,all [a,b,c] witnesses with aRb and bRc but not aRc,transitive?). Preserve the nested lexicographic order of the two supplied relation pairs. Despite the source field name missing_transitive_pairs, the records are triples.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
