Their sums vanish, and the gcd of all twenty-four coordinates is one, so this representative is centered and primitive. Direct summation gives equal powers for \\(1\\leq k\\leq11\\). At \\(k=12\\), the difference \\(\\sum_Aa^{12}-\\sum_Bb^{12}\\) is\n\\[\n809283534716112648192000.\n\\]\nThe two monic root polynomials differ by the nonzero constant\n\\[\n-67440294559676054016000.\n\\]\nThis certifies a nontrivial ideal solution of size twelve. It supplies a control for the definitions and gives no size-eleven witness.\n\nThe four-line output has SHA-256 digest `0617ec2157d54c020ce602649b765768866531635ca4c54ea3484e0ebebe2fb6`.",
