Proof step 1 from proof and-notempty-06 (conclusion)

⊦ bitsand(boolvar ' + bits, boolvar0 ' + bits0) ≠ []

Heuristic simplifier applied rule simplifier

And closed the goal!

Rule argument

Additional information

Used simplifier rules: and-notempty-05: ⊦ bitsand(boolvar0 ' + bits, boolvar ' + bits0) ≠ [];% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;
