Proof step 5 from proof cong-crt (previous step)

≡mod(i, 1, j), ≡mod(i, 1, j0), prime(j), prime(j0), 0 < i ⊦ j = j0, j * j0 | i - 1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ ≡mod(i, i0, j) ↔ j | abs(i - i0)
Proof step 7:
≡mod(i, 1, j), j0 | abs(i - 1), prime(j), prime(j0), 0 < i ⊦ j = j0, j * j0 | i - 1

Rule argument

spec: int-mod inst: name: congmod-def seq: ⊦ ≡mod(i, i0, j) ↔ j | abs(i - i0) subst: [j, i0, i] → [j0, 1, i] flags: rewrite, current
