# Question 16235: A DFA Needs a Complete Total Deterministic Transition Table [Return to catalogue page 82](https://ocme.evemisslab.com/en/questions/page/82/) [← Question derivation index](https://ocme.evemisslab.com/en/questions/) · [Original question batch](https://ocme.evemisslab.com/en/practice/batch-20261014-advance-20261101-r07-finite-automaton-foundations/#q-20261014-advance-20261101-r07-finite-automaton-0010) 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. R0031-16235 · q-20261014-advance-20261101-r07-finite-automaton-0010 ## Original question and givens Use a complete deterministic finite automaton with states=Fin(3)={0,…,2}, alphabet=Fin(2)={0,…,1}, total row-state/column-symbol transition=[[0, 0], [1, 0], [0, 0]], unique start=0, and increasing accepting subset=[0]. Every transition output lies in this same state set. There are no epsilon transitions or nondeterministic branches. Read a finite word in symbol order; the empty word leaves the automaton at its start state. Give (state_count,alphabet_count,start,accepting,transition_cell_count,qualified?,complete_total_deterministic_table). - G001 — Use a complete deterministic finite automaton with states=Fin(3)={0,…,2}, alphabet=Fin(2)={0,…,1}, total row-state/column-symbol transition=[[0, 0], [1, 0], [0, 0]], unique start=0, and increasing accepting subset=[0].

Read a finite word in symbol order; the empty word leaves the automaton at its start state. Give (state_count,alphabet_count,start,accepting,transition_cell_count,qualified?,complete_total_deterministic_table). ## 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-finite-automaton](https://ocme.evemisslab.com/en/mko/mko-finite-automaton/) ## Step-by-step derivation S001 · calculationBefore DFA total state-symbol cell count := mul(3, 2) After DFA total state-symbol cell count = 6 Conditions: none Compute exactly from original field roles and established intermediates,retaining denominators,signs,indices and the complete carrier.
