Original question and givens

Use complete qualified finite group Cayley tables with carrier labels 0 through size−1 and the given row/column order. Every group axiom is a premise already checked on the whole table. Results concern these finite groups; a homomorphism need not be injective or an isomorphism. source size=6, source table=[[4, 0, 3, 5, 1, 2], [0, 1, 2, 3, 4, 5], [3, 2, 0, 4, 5, 1], [5, 3, 4, 1, 2, 0], [1, 4, 5, 2, 0, 3], [2, 5, 1, 0, 3, 4]], target size=3, target table=[[2, 0, 1], [0, 1, 2], [1, 2, 0]], mapping=[2, 1, 0, 1, 0, 2]. Require this map to preserve all source products. Give (source size,target size,mapping,source labels mapping to the target identity,sorted distinct image,injective?).

The kernel maps to the actual target identity;the image is the distinct mapping values.A finite total map is injective exactly when image size equals source size.A constant homomorphism need not be injective.This is a mathematical kernel,not a software-kernel receipt.
