Proof step 4 from proof coprimes-one (previous step)

⊦ filterFun(λ j. true, 1 ') = 1 '

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: inst: name: filterFun-one seq: ⊦ filterFun(intboolfun, i ') = (intboolfun(i) ⊃ i ';[]) subst: [i, intboolfun] → [1, λ j. true] flags: rewrite, current

Additional information

Used simplifier rules: c-04: ⊦ i ' = i0 ' ↔ i = i0; from specification list[intlista] Used terms: 1, λ j. true
