Proof step 2 from proof int2bytes-len-one (previous step)

int2bytes(i) = by ' ⊦ i = b2i(by)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
~128 ≤ i, i < 128 ⊦ int2bytes((* i)) = i2b(i) '
Proof step 4:
¬(~128 ≤ i ∧ i < 128), int2bytes(i) = by ' ⊦ i = b2i(by)
Proof step 15:
~128 ≤ i ∧ i < 128, i2b(i) ' = by ' ⊦ i = b2i(by)

Rule argument

name: int2bytes-byte rotate: F subst: [i] → [i]
