Original question and givens

Use complete Cayley table=[[0, 1], [1, 0]] with row g/column h giving g*h, declared identity=0, point carrier Fin(5)={0,…,4}, and total action_table=[[0, 1, 2, 3, 4], [1, 0, 2, 3, 4]] with row g/column x giving g*x. Check the full group axioms separately from e*x=x and (g*h)*x=g*(h*x). Permutation rows alone are not an action certificate. Give (triple_count, first_failure, compatible, certificate).

  • G001 — Use complete Cayley table=[[0, 1], [1, 0]] with row g/column h giving g*h, declared identity=0, point carrier Fin(5)={0,…,4}, and total action_table=[[0, 1, 2, 3, 4], [1, 0, 2, 3, 4]] with row g/column x giving g*x. Check the full group axioms separately from e*x=x and (g*h)*x=g*(h*x). Permutation rows alone are not an action certificate. Give (triple_count, first_failure, compatible, certificate).

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 operation=groupaction-compatibility-audit;original snapshot and mathematics retained

After

explicit ordered source output fields=[triple_count, first_failure, compatible, certificate]

Conditions: none

Retain the historical interface marker in the original snapshot while listing ordered source fields here,without JavaScript or external lookup.Field labels are not additional mathematical evidence,and No retains the source claim scope.

Step identifiers and dependencies

Rule: source_ordered_interface_explicit_without_javascript · Uses: G001

S002 · implies

Before

ORIGINAL complete group-label carrier Fin(2);declared identity label=0;Cayley table row g,column h gives g*h=[[0, 1], [1, 0]]

After

ORIGINAL complete point carrier Fin(5);TOTAL action table row g,column x gives g*x=[[0, 1, 2, 3, 4], [1, 0, 2, 3, 4]];all entries in range,so structural closure/totality checked;GROUP AXIOMS not assumed from shape

Conditions: none

The two tables have different column roles:group label h versus action point x.Complete in-range tables establish closure/totality only.A candidate group may fail its axioms;its table name does not certify them.

S003 · implies

Before

ORIGINAL ordered group pair(g,h)=[0, 0];actual group product=0;action table roles unchanged

Conditions: none

For the left side compute the group product before acting;for the right act by h and then g,without interchanging them.Check every point for every ordered pair and retain the first lexicographic g,h,x failure.

S007 · calculation

Before

group action ordered group-pair count := mul(2, 2)

After

group action ordered group-pair count = 4

Conditions: none

Substitute original roles and established intermediates exactly,retaining indices,signs,denominators and the proof's applicability conditions.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S006

S008 · calculation

Before

group action complete triple-domain count := mul(4, 5)

After

group action complete triple-domain count = 20

Conditions: none

Substitute original roles and established intermediates exactly,retaining indices,signs,denominators and the proof's applicability conditions.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S007

S009 · implies

Before

COMPLETE triple domain order^2*point_count=20;this derivation ACTUALLY checked all20 triples

After

compatibility=Yes;FIRST source-order failure[g,h,x,left,right]=null;null means NO failure anywhere

Conditions: none

The triple_count is the complete quantified domain size,not a measurement of an early-stopping prototype.This derivation actually checks every point for every g,h pair,so null certifies full compatibility and a first failure retains exact source data/order.

Step identifiers and dependencies

Rule: groupaction_full_domain_count_first_failure_not_early_stop_measurement · Uses: G001, S008

S010 · implies

Before

this component audited ALL group-group-point compatibility triples

After

compatibility flag alone does NOT establish identity-action or group qualification

Conditions: none

Complete compatibility is one obligation,not a replacement for e*x=x or group qualification.Even passing this component does not additionally claim a valid action.

Rule: groupaction_compatibility_component_not_full_action_claim · Uses: G001, S009

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