Proof step 33 from proof diff-primes-dups (previous step)

0 ≤ j0, 0 ≤ j, prime(j), j0 ≤ (j - 1) / 2 ⊦ j = 2, dups(countFun(0, (j - 1) / 2, λ i. (~1 - i ^2) |%| j)), dups(countFun(0, (j - 1) / 2, λ i. i ^2 |%| j)), dups(countFun(0, (j - 1) / 2, λ i. i ^2 |%| j) + countFun(0, (j - 1) / 2, λ i. (~1 - i ^2) |%| j)), 0 ≤ (~1 - j0 ^2) |%| j ∧ (~1 - j0 ^2) |%| j < j
