Proof step 6 from proof cyclic-ncyclic (previous step)

reachable-n(H, n, r, r) ⊦ reachable-n(H, n0 * n, r, r)

User applied rule structural induction

And obtained the following new goals

Proof step 3:
reachable-n(H, n, r, r) ⊦ reachable-n(H, 0 * n, r, r)
Proof step 5:
∀ H, n, r. reachable-n(H, n, r, r) → reachable-n(H, n1 * n, r, r), reachable-n(H, n, r, r) ⊦ reachable-n(H, n1 +1 * n, r, r)

Rule argument
