Proof step 12 from proof bytes2int-diff (previous step)

# bytes0 = 1, bytes2int(bytes0) = b2i(by), ∀ bytes0, bytes1. # bytes1 < 1 → # bytes0 = # bytes1 ∧ bytes2int(bytes0) = bytes2int(bytes1) → bytes0 = bytes1 ⊦ bytes0 = by '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
⊦ # bytes = 1 ↔ bytes = bytes.first + []
Proof step 14:
bytes0 = bytes0.first + [], bytes2int(bytes0) = b2i(by), ∀ bytes0, bytes1. # bytes1 < 1 → # bytes0 = # bytes1 ∧ bytes2int(bytes0) = bytes2int(bytes1) → bytes0 = bytes1 ⊦ bytes0 = by '

Rule argument

seq: ⊦ # bytes = 1 ↔ bytes = bytes.first + [] subst: [bytes] → [bytes0] rotate: F spec: list-data inst: bytelist name: lf-01
