Proof step 1035 from proof bitsand-cast (previous step)

# bits0 ≠ 0, # bits0 < # bits1 ⊦ bits1 = [], bits0 = [], bits2 + bits1 = [], bits1 = mklist(false, # bits1 - # bits0) + mklist(false, # bits0), true ∈ bits1, bits0.first

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1036:
# bits0 < # bits1 ⊦ bits1 = [], bits0 = [], bits2 + bits1 = [], bits1 = mklist(false, # bits1 - # bits0) + mklist(false, # bits0), true ∈ bits1, bits0.first

Rule argument

Additional information

Used simplifier rules: ⊦ # bits = 0 ↔ bits = [];
