Use prime=3, original a=1. Give (prime, a, normalized_class, odd_prime, nonzero_class, certificate).
G001 — Use prime=3, original a=1. Give (prime, a, normalized_class, odd_prime, nonzero_class, certificate).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.
Before
source roles = [eulercrit-domain-qualification]
After
derived = [[prime, a, normalized_class, odd_prime, nonzero_class, certificate]]
Conditions: none
List the source field order without JavaScript.Gradient boundary uses its original mode to choose6,8 or7 fields;no padding or answer-derived mode.
Rule: source_ordered_fields_without_JS · Uses: G001
Before
source roles = [3]
After
derived = [[], Yes]
Conditions: none
A composite has a factor at most its square root;complete trial division qualifies the modulus,not a guessed square/Euler equality.
Rule: Euler_modulus_primality_complete_trial · Uses: G001, S001
Before
Euler ORIGINAL signed quotient times modulus := mul(0, 3)
After
Euler ORIGINAL signed quotient times modulus = 0
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
Euler ORIGINAL signed a minus modulus multiple := sub(1, 0)
After
Euler ORIGINAL signed a minus modulus multiple = 1
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S003
Before
source roles = [1, 3, 0]
After
derived = [1, Yes]
Conditions: none
Use a=qp+r with0<=r<p,including negative a;retain original a where the interface requests it.
Rule: Euler_Euclidean_class_before_hypothesis · Uses: G001, S004
Before
source roles = [3, 1, 1]
After
derived = [Yes, Yes]
Conditions: none
Qualify odd primality and the nonzero class first.Define Legendre by the square table before comparing a power.
Rule: Euler_odd_prime_nonzero_qualified · Uses: G001, S005
Before
Euler square root candidate1 := mul(1, 1)
After
Euler square root candidate1 = 1
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S006
Before
Euler square root candidate2 := mul(2, 2)
After
Euler square root candidate2 = 4
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S007
Before
source roles = [3, 1]
After
derived = [[[1, 1], [2, 1]], [1, 2], 1]
Conditions: none
Enumerate every nonzero square;roots give+1 and complete absence gives−1.This route does not use Euler criterion to compute Legendre.
Rule: Euler_ALL_nonzero_square_table_defines_Legendre · Uses: G001, S008
Before
Euler binary power accumulate0 := mul(1, 1)
After
Euler binary power accumulate0 = 1
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S009
Before
Euler binary power square0 := mul(1, 1)
After
Euler binary power square0 = 1
Conditions: none
Substitute original roles and established intermediates exactly;check nonzero denominators and do not round.
Rule: exact_rational_arithmetic · Uses: G001, S010
Before
source roles = [0, [1, 1, 1], 3, 1, 1]
After
derived = [1, 1, 1, 1, 0]
Conditions: none
Maintain acc*base^remaining congruent to the original half-power:accumulate an odd bit,square the base,and halve the exponent to0.This is separate from the square-table calculation.
Rule: Euler_repeated_squaring_original_exponent_invariant · Uses: G001, S011
Before
source roles = [3, [1, 2], 1, 1]
After
derived = [1, Yes, one finite instance is not a general theorem proof]
Conditions: none
p−1 represents−1 modulo p,not integer equality.Compare the two computations for this instance;one finite table is not a general theorem proof.
