Proof step 11 from proof bitsand-app (previous step)

# bits1 = # bits4, ∀ bits2, bits0, bits, bits3. # bits3 < #(bits4 + boolvar ') → # bits = # bits3 → bits0 = [] ∨ bits2 = [] ∨ bits = [] ∨ bitsand(bits0 + bits, bits2 + bits3) = bitsand(bits0, bits2) + bitsand(bits, bits3) ⊦ bits2 = [], bits0 = [], bitsand(bits0 + bits1, bits2 + bits4) + (boolvar0 ∧ boolvar)' = bitsand(bits0, bits2) + bitsand(bits1 + boolvar0 ', bits4 + boolvar ')

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

name: and-rec rotate: F subst: [bits0, bits] → [bits4 + boolvar ', bits1 + boolvar0 ']

Additional information

Used terms: bits4 + boolvar ', bits1 + boolvar0 '
