Proof step 56 from proof bytes2bytes-fix (previous step)

∀ bytes0. # bytes0 < # bytes → true → bytes0 = [] ∨ fix(# bytes0, int2bytes(bytes2int(bytes0))) = bytes0 ⊦ bytes = [], b2i(bytes.first) = 0, b2i(bytes.first) = ~1, fix(# bytes, bytes) = bytes

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 57:
⊦ # bytes = n → fix(n, bytes) = bytes

Rule argument

name: fix-length-01 rotate: F subst: [bytes, n] → [bytes, # bytes]

Additional information

Used terms: bytes, # bytes
