# int2bits(i) = i→n(j), 0 ≤ i ⊦ bits2int(firstn(n0 + i→n(j), mklist(false, i→n(j)) + mklist(false, n0) + int2bits(i))) = 0, j = 0, mklist(false, i→n(j) + n0) = mklist(false, n0) + mklist(false, i→n(j)), n0 = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ mklist(boolvar, m) + mklist(boolvar, n) = mklist(boolvar, m + n) subst: [n, m, boolvar] → [i→n(j), n0, false] rotate: F spec: list-last inst: bitlista name: mklist-append

Additional information

Used simplifier rules: ⊦ m + n = n + m; Used terms: i→n(j), n0, false
