Question 29295: Closure of Every Cell in a Complete Cayley Table

Original question and givens

The complete finite Cayley table=[[2, 4, 3, 1, 0], [4, 3, 0, 2, 1], [3, 0, 1, 4, 2], [1, 2, 4, 0, 3], [0, 1, 2, 3, 4]] uses elements Fin(5)={0,…,4} and entry table[a][b]=a*b. Preserve element labels and row/column order. A sampled row or triple does not prove the group axioms. This family permits out-of-carrier entries to test qualification. Give (carrier size,table,does every entry lie in the carrier?).

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

source roles = [qf-str22-group-table-qualification, group-table-qualification]

derived = [[n, table, closed]]

source roles = [5, 0, [2, 4, 3, 1, 0]]

derived = [[Yes, Yes, Yes, Yes, Yes]]

source roles = [5, 1, [4, 3, 0, 2, 1]]

derived = [[Yes, Yes, Yes, Yes, Yes]]

source roles = [5, 2, [3, 0, 1, 4, 2]]

derived = [[Yes, Yes, Yes, Yes, Yes]]

source roles = [5, 3, [1, 2, 4, 0, 3]]

derived = [[Yes, Yes, Yes, Yes, Yes]]

source roles = [5, 4, [0, 1, 2, 3, 4]]

derived = [[Yes, Yes, Yes, Yes, Yes]]

source roles = [5, [[2, 4, 3, 1, 0], [4, 3, 0, 2, 1], [3, 0, 1, 4, 2], [1, 2, 4, 0, 3], [0, 1, 2, 3, 4]]]

derived = [Yes]

Result

(5, [[2, 4, 3, 1, 0], [4, 3, 0, 2, 1], [3, 0, 1, 4, 2], [1, 2, 4, 0, 3], [0, 1, 2, 3, 4]], Yes)

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