Proof step 15 from proof bitsor-bi-ones (previous step)

¬(# bits0 = # bits2 ∧ bits3 ≠ [] ∧ bits0 ≠ [] ∧ true ' ≠ [] ∧ bits2 ≠ []), # bits0 = # bits2 ⊦ bits3 + bits0 = [], bits2int(bitsor(bits3 + bits0, true ' + bits2) + bits1) = bits2int(true ' + bits1), # bits3 = 1, bits3 = [], false ∈ bits3, false ∈ bits0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
# bits0 = # bits2 ⊦ bits3 + bits0 = [], bits2int(bitsor(bits3 + bits0, true ' + bits2) + bits1) = bits2int(true ' + bits1), # bits3 = 1, bits3 = [], false ∈ bits3, false ∈ bits0, bits0 ≠ [] ∧ bits2 ≠ []
