Proof step 1 from proof rangeeq-write-left-below (conclusion)

n < m0 ⊦ range=(ar0[n, a], m0, ar1, m1, m) ↔ range=(ar0, m0, ar1, m1, m)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
n < m0 ⊦ range=(ar0[n, a], m0, ar1, m1, m) ↔ range=(ar0, m0, ar1, m1, m)

Rule argument

Additional information

Used simplifier rules: ⊦ m < n → n ≠ 0; (s)%f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic
