Proof step 3 from proof inv-mklist (previous step)

∀ boolvar. bitsinvert(mklist(boolvar, m)) = mklist(¬ boolvar, m) ⊦ bitsinvert(boolvar ' + mklist(boolvar, m)) = (¬ boolvar)' + mklist(¬ boolvar, m)

Heuristic cut applied rule cut formula

And obtained the following new goals

Proof step 4:
¬ boolvar, ∀ boolvar. bitsinvert(mklist(boolvar, m)) = mklist(¬ boolvar, m) ⊦ bitsinvert(boolvar ' + mklist(boolvar, m)) = (¬ boolvar)' + mklist(¬ boolvar, m)
Proof step 6:
∀ boolvar. bitsinvert(mklist(boolvar, m)) = mklist(¬ boolvar, m) ⊦ ¬ boolvar, bitsinvert(boolvar ' + mklist(boolvar, m)) = (¬ boolvar)' + mklist(¬ boolvar, m)

Rule argument

fma: ¬ boolvar
