Proof step 61 from proof fix-bits2bytes-01 (previous step)

# bits = 8 * n0 ⊦ n0 = 0, bits = [], fix(n0, bits2bytes(bits)) = bits2bytes(bits)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 62:
⊦ # bytes ≥ n → fix(n, bytes) = lastn(n, bytes)
Proof step 63:
¬ # bits2bytes(bits) ≥ n0, # bits = 8 * n0 ⊦ n0 = 0, bits = [], fix(n0, bits2bytes(bits)) = bits2bytes(bits)
Proof step 66:
# bits2bytes(bits) ≥ n0, # bits = 8 * n0 ⊦ n0 = 0, bits = [], lastn(n0, bits2bytes(bits)) = bits2bytes(bits)

Rule argument

name: fix-longer rotate: F subst: [bytes, n] → [bits2bytes(bits), n0]
