Proof step 3 from proof mk-inj-01 (previous step)

∀ a, n. mklist(a, m0) = mklist(a, n) → m0 = n, mklist(a, m0 +1) = mklist(a, n) ⊦ m0 +1 = n

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
mklist(a, m0 + 1) = mklist(a, n), ∀ a, n. mklist(a, m0) = mklist(a, n) → m0 = n ⊦ m0 + 1 = n

Rule argument

Additional information

Used simplifier rules: succ: ⊦ m +1 = m + 1; from specification nat-basic2
