Proof step 2 from proof and-onel-01 (previous step)

⊦ bits = [], bitsand(true ', bits) = bits

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ bits0 ≠ [] ∧ bits = true ' → bitsand(bits, bits0) = bits0

Rule argument

name: and-rec-03 rotate: F subst: [bits0, bits] → [bits, true ']

Additional information

Used terms: bits, true '
