Proof step 4 from proof band-zero (previous step)

⊦ bits2int(bitsand(false ', int2bits(i))) = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ bits0 ≠ [] ∧ bits = false ' → bitsand(bits, bits0) = false '

Rule argument

name: and-rec-04 rotate: F subst: [bits0, bits] → [int2bits(i), false ']

Additional information

Used simplifier rules: ⊦ int2bits(j) ≠ [];% ⊦ bits2int(false ') = 0; Used terms: int2bits(i), false '
