Proof step 78 from proof shiftright-rec-pos (previous step)

0 ≤ i, 0 ≤ i0, 1 < i, 0 < i ⊦ bits2uint(firstn(# int2bits(i / 2), mklist(false, i→n(i0)) + int2bits(i / 2))) = bits2int(firstn(# int2bits(i / 2), mklist(false, i→n(i0)) + int2bits(i / 2)))

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ ¬ bits.first ∧ bits ≠ [] → bits2int(bits) = bits2uint(bits) subst: [bits] → [firstn (# int2bits(i / 2), mklist(false, i→n(i0)) + int2bits(i / 2))] rotate: F spec: int2bits inst: name: bits2int-pos-02

Additional information

Used terms: firstn(# int2bits(i / 2), mklist(false, i→n(i0)) + int2bits(i / 2))
