Proof step 4 from proof and-one (previous step)

⊦ bitsand(boolvar ', false ') = false '

User applied rule insert rewrite lemma

And obtained the following new goals

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

Rule argument

name: and-rec-02 rotate: F subst: [bits0, bits] → [false ', boolvar ']

Additional information

Used simplifier rules: ⊦ boolvar ' ≠ []; Used terms: false ', boolvar '
