Proof step 13 from proof fix-rec-neg (previous step)

b2i(by) < 0, 1 + # bytes0 < n, bytes2int(by ' + bytes0) < 0, # bytes0 + 1 < n ⊦ mklist(i2b(~1), n - 1 + # bytes0) = i2b(~1) ' + mklist(i2b(~1), n - 1 - 1 + # bytes0)

User applied rule insert elim lemma

And obtained the following new goals

Proof step 14:
n = m + 1 ∧ n ≠ 0, b2i(by) < 0, 1 + # bytes0 < n, bytes2int(by ' + bytes0) < 0, # bytes0 + 1 < n ⊦ mklist(i2b(~1), n - 1 + # bytes0) = i2b(~1) ' + mklist(i2b(~1), m - 1 + # bytes0)

Rule argument

seq: n ≠ 0 ⊦ m = n - 1 ↔ n = m + 1 subst: [n, m] → [n, m] rotate: T spec: nat inst: name: elim-pred-c

Additional information

Used simplifier rules: ⊦ m + n = n + m;% ⊦ bytes = bytes0 + bytes ↔ bytes0 = [];% ⊦ by ' ≠ [];% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1;%n0 < n ⊦ ¬ m + (* n) < (* n0);% ⊦ (m + n0) + n1 = m + n0 + n1;%n ≠ 0 ⊦ m = n - 1 ↔ n = m + 1; (elim) Used terms: n, m
