Proof step 698 from proof bitsand-cast (previous step)

mklist(false, # bits3) ≠ [], # bits1 = 2 + # bits, # bits3 < m ⊦ mklist(false, m) = mklist(mklist(false, # bits3).first, m - # bits3) + mklist(false, # bits3), bits2 + mklist(false, m) = [], bits3 + bits1 = [], bits3 = [], bits1 = [], mklist(false, # bits3) + bitsand(bits1, false ' + true ' + bits) = [], # bits3 = m, bits3.first

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 699:
# bits1 = 2 + # bits, # bits3 < m ⊦ mklist(false, m) = mklist(mklist(false, # bits3).first, m - # bits3) + mklist(false, # bits3), bits2 + mklist(false, m) = [], bits3 + bits1 = [], bits3 = [], bits1 = [], mklist(false, # bits3) + bitsand(bits1, false ' + true ' + bits) = [], # bits3 = m, bits3.first

Rule argument

Additional information

Used simplifier rules: ⊦ # bits = 0 ↔ bits = [];% ⊦ mklist(boolvar, m) = [] ↔ m = 0;
