Proof step 11 from proof mk-inj-01 (previous step)

n = m + 1, mklist(a, m0) = mklist(a, m), ∀ a, n. mklist(a, m0) = mklist(a, n) → m0 = n ⊦ m0 + 1 = n, n = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
mklist(a, m0) = mklist(a, m), ∀ a, n. mklist(a, m0) = mklist(a, n) → m0 = n ⊦ m0 = m
