Original question and givens

Use mode=wrong_quantifiers, complete model={"p":18,"word":["a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","b"]}. Give (mode, p, word, legal_split_count, adversarial_choice_order, reversed_quantifier_claim).

  • G001 — Use mode=wrong_quantifiers, complete model={"p":18,"word":["a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","a","b"]}. Give (mode, p, word, legal_split_count, adversarial_choice_order, reversed_quantifier_claim).

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.

Step-by-step derivation

S001 · implies

Before

source roles = [pump-boundary]

After

derived = [[mode, p, word, legal_split_count, adversarial_choice_order, reversed_quantifier_claim]]

Conditions: none

List the complete source field order and mode-specific roles without JavaScript or answer-shape inference;No,undefined and infinity retain their distinct meanings.

Step identifiers and dependencies

Rule: source_ordered_fields_without_JS · Uses: G001

S002 · implies

Before

source roles = [wrong_quantifiers, 18, [a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, b]]

After

derived = [171, adversary_word_then_prover_split_then_adversary_i, No]

Conditions: none

A nonregularity argument chooses a member word for arbitrary p,then defeats EVERY legal split the prover may choose with a pump count i.Do not swap those choices or attack only a preselected split.

Step identifiers and dependencies

Rule: Pumping_adversarial_choice_order_AND_ALL_splits_obligation · Uses: G001, S001

Reverse checks

  • S002 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.
  • S001 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.

Result

(wrong_quantifiers, 18, [a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, b], 171, adversary_word_then_prover_split_then_adversary_i, No)

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
