And obtained the following new goals

Proof step 57:
⊦ ¬ false ∈ bits ∧ # bits0 ≤ # bits ∧ bits0.first ∧ bits0 ≠ [] → bitsand(bits0, bits) = fillsgn(# bits, bits0)
Proof step 58:
¬ false ∈ mklist(true, i→n(i)) ∧ # bitsinvert(int2bits(j0)) ≤ # mklist(true, i→n(i)) ∧ bitsinvert(int2bits(j0)).first ∧ bitsinvert(int2bits(j0)) ≠ [], int2bits(j0) = false ' + bitsinvert(bits), 0 < j, j0 < 2 ^ i, 0 ≤ i, 0 ≤ j0, 0 < 2 ^ i, 0 ≤ j, # int2bits(j0) ≤ i→n(i), false ∈ int2bits(j0) ⊦ bitsinvert(uint2bits(j)) + mklist(true, i→n(i)) = [], bits2uint(bitsinvert(fillsgn(# mklist(true, i→n(i)), bitsinvert(int2bits(j0))))) + 2 ^ n→i(# fillsgn(# mklist(true, i→n(i)), bitsinvert(int2bits(j0)))) * j = j * 2 ^ i + j0, fillsgn(# mklist(true, i→n(i)), bitsinvert(int2bits(j0))) = []
