Proof step 24 from proof band-65535-pos (previous step)

8 * 2 < # bytes * 8, 8 * 2 + 1 < # bytes * 8, 0 < bytes2int(bytes), # bytes ≤ 2 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 25:
⊦ m * n = n * m
Proof step 26:
8 * 2 < 8 * # bytes, 8 * 2 + 1 < 8 * # bytes, 0 < bytes2int(bytes), # bytes ≤ 2 ⊦

Rule argument

seq: ⊦ m * n = n * m subst: [n, m] → [8, # bytes] rotate: F spec: nat-mult inst: name: mult-c
