# Question 27750: A Composite Factorial Computation Is an Instance, Not the Converse Proof [Return to catalogue page 139](https://ocme.evemisslab.com/en/questions/page/139/) [← Question derivation index](https://ocme.evemisslab.com/en/questions/) · [Original question batch](https://ocme.evemisslab.com/en/practice/batch-20261015-advance-20261118-r04-wilson-theorem-foundations/#q-20261015-advance-20261118-r04-wilson-theorem-0075) This teaching derivation has second-context AI mathematical and bilingual semantic review, limited to the model and assumptions stated in this question. It has no human review or new Lean proof and does not promote the original question or MKO to Canonical truth. R0054-27750 · q-20261015-advance-20261118-r04-wilson-theorem-0075 ## Original question and givens Use composite integer n=38. Give (n, prime, running_factorial_residues, factorial_residue, minus_one_residue, Wilson_congruence_fails, finite_scope). - G001 — Use composite integer n=38. Give (n, prime, running_factorial_residues, factorial_residue, minus_one_residue, Wilson_congruence_fails, finite_scope). ## 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. - [mko-wilson-theorem](https://ocme.evemisslab.com/en/mko/mko-wilson-theorem/) ## Step-by-step derivation S001 · impliesBefore source roles = [wilson-composite-instance] After derived = [[n, prime, running_factorial_residues, factorial_residue, minus_one_residue, Wilson_congruence_fails, finite_scope]] Conditions: none List the complete operation/mode field order without JavaScript or answer-shape inference;Boolean,string,null and an unclaimed result remain distinct.
