Proof step 391 from proof bitsand-cast (previous step)

# bits1 = 2 + # bits, sgn(mklist(boolvar, n - 1) + boolvar ' + boolvar0 ' + bits) = boolvar ' + boolvar0 ' + bits ⊦ bits3 = [], lastn(n + 1 + # bits, fillsgn(n + 1 + # bits, bitsand(bits3 + bits1, boolvar ' + boolvar0 ' + bits))) = lastn(n + 1 + # bits, fillsgn(n + 1 + # bits, bitsand((bits2 + mklist(boolvar, n - 1)) + boolvar ' + boolvar0 ' + bits, bits3 + bits1))), n = 0, boolvar ↔ boolvar0, bits3 + bits1 = [], boolvar ∧ boolvar0

User applied rule insert rewrite lemma

And obtained the following new goals
