Proof step 2 from proof datasize-samebuf-h (previous step)

datasize(buf, n) < datasize(buf, m), m < n, n ≤ # buf, m ≤ # buf ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
m < n, datasize(buf, n) < datasize(buf, m), m < # buf, n ≤ # buf ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ m < n → m ≤ n; (s)% ⊦ m < n → n ≠ 0; (s)%fle: ⊦ m < n ∧ n ≤ n0 → m < n0; (forward) from specification nat%f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic
