Proof step 3 from proof s-04 (previous step)

∀ m. m < n0 + 1 ↔ ¬ n0 < m ⊦ m < 2 + n0 ↔ ¬ n0 + 1 < m

Heuristic cut applied rule cut formula

And obtained the following new goals

Rule argument

fma: m < 2 + n0

Additional information

Used simplifier rules: f: ⊦ m < n → n ≠ 0;%trans-01: ⊦ n < n0 ∧ n0 < n1 → n +1 < n1;%trans: ⊦ n < n0 ∧ n0 < n1 → n < n1;%succ: ⊦ m +1 = m + 1;%a: ⊦ (m + n0) + n1 = m + n0 + n1;%c: ⊦ m + n = n + m;%l: ⊦ m + n < m + n0 ↔ n < n0;%ref: ⊦ ¬ n < n; Used formulas: m < 2 + n0
