1. An Integral Domain Requires Every Nonzero Pair to Avoid Zero

Use the same qualified complete finite commutative unital ring on Fin(4)={0,…,3}, with addition=[[0, 1, 2, 3], [1, 2, 3, 0], [2, 3, 0, 1], [3, 0, 1, 2]] and multiplication=[[0, 0, 0, 0], [0, 1, 2, 3], [0, 2, 0, 2], [0, 3, 2, 1]] in carrier-label order. All ring axioms and distinct two-sided identities already hold; the zero and one labels need not be 0 and 1. No nonzero-zero-divisor or field premise is silently added. Give (n,zero,one,zero_divisor_pairs,domain?,classification). List all ordered nonzero [a,b] with a*b=zero in increasing a then b order. Classification is finite_integral_domain or commutative_ring_with_zero_divisors.

View answer and explanation

(4, 0, 1, [[2, 2]], No, commutative_ring_with_zero_divisors)

Use the actual additive zero, not its presumed label. A complete absence of such pairs qualifies this finite integral domain. Invertibility is a subsequent theorem using finiteness, not an extra definition clause. The exact result, retaining the requested order, is (4, 0, 1, [[2, 2]], No, commutative_ring_with_zero_divisors).

View answer and explanation

(2, 1, 2, Yes, finite_injective_multiplication_implies_surjective)

Multiplication by a nonzero element is injective by cancellation. Because this carrier is finite it is also surjective, so the actual identity has a preimage. Return the first inverse in increasing carrier-label order; do not extend this finite step to arbitrary infinite domains. The exact result, retaining the requested order, is (2, 1, 2, Yes, finite_injective_multiplication_implies_surjective).

98. Keep the Finite Step from Integral Domain to Invertibility

Use the same qualified complete finite commutative unital ring on Fin(5)={0,…,4}, with addition=[[0, 1, 2, 3, 4], [1, 4, 3, 0, 2], [2, 3, 1, 4, 0], [3, 0, 4, 2, 1], [4, 2, 0, 1, 3]] and multiplication=[[0, 0, 0, 0, 0], [0, 2, 3, 4, 1], [0, 3, 4, 1, 2], [0, 4, 1, 2, 3], [0, 1, 2, 3, 4]] in carrier-label order. All ring axioms and distinct two-sided identities already hold; the zero and one labels need not be 0 and 1. No nonzero-zero-divisor or field premise is silently added. Additionally require an integral domain and nonzero element=1. Give (element,one,inverse,found?,finite_injective_multiplication_implies_surjective).

View answer and explanation

(1, 4, 3, Yes, finite_injective_multiplication_implies_surjective)

Multiplication by a nonzero element is injective by cancellation. Because this carrier is finite it is also surjective, so the actual identity has a preimage. Return the first inverse in increasing carrier-label order; do not extend this finite step to arbitrary infinite domains. The exact result, retaining the requested order, is (1, 4, 3, Yes, finite_injective_multiplication_implies_surjective).
