Proof step 2 from proof RSA-decrypt-ij-vars (previous step)

gcd(i2, (i - 1) * (i0 - 1)) = 1, 0 < i2, 0 < i, j < i * i0, ≡mod(i2 * i3, 1, (i - 1) * (i0 - 1)), i2 < i * i0, 2 < i0, 2 < i, prime(i0), prime(i), 0 ≤ j, 0 ≤ i3, 0 < i0, 1 < i * i0 ⊦ i = i0, j = (j ^ i2 |%| (i * i0)) ^ i3 |%| (i * i0)

And obtained the following new goals

Proof step 3:
i3 = 0, gcd(i2, (i - 1) * (i0 - 1)) = 1, 0 < i2, 0 < i, j < i * i0, ≡mod(i2 * i3, 1, (i - 1) * (i0 - 1)), i2 < i * i0, 2 < i0, 2 < i, prime(i0), prime(i), 0 ≤ j, 0 ≤ i3, 0 < i0, 1 < i * i0 ⊦ i = i0, j = (j ^ i2 |%| (i * i0)) ^ i3 |%| (i * i0)
Proof step 12:
gcd(i2, (i - 1) * (i0 - 1)) = 1, 0 < i2, 0 < i, j < i * i0, ≡mod(i2 * i3, 1, (i - 1) * (i0 - 1)), i2 < i * i0, 2 < i0, 2 < i, prime(i0), prime(i), 0 ≤ j, 0 ≤ i3, 0 < i0, 1 < i * i0 ⊦ i3 = 0, i = i0, j = (j ^ i2 |%| (i * i0)) ^ i3 |%| (i * i0)

Rule argument
