Proof step 15 from proof fix-rec-neg (previous step)

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

User applied rule insert elim lemma

And obtained the following new goals

Proof step 16:
m = n + # bytes0 ∧ # bytes0 ≤ m, bytes2int(by ' + bytes0) < 0, # bytes0 < m, b2i(by) < 0 ⊦ mklist(i2b(~1), n) = i2b(~1) ' + mklist(i2b(~1), m - 1 + # bytes0)

Rule argument

seq: n ≤ m ⊦ n0 = m - n ↔ m = n0 + n subst: [m, n, n0] → [m, # bytes0, n] rotate: T spec: nat inst: name: elim-sub

Additional information

Used simplifier rules: ⊦ ¬ m ≤ n ↔ n < m;% ⊦ m < n → ¬ n < m;%n ≤ m ⊦ n0 = m - n ↔ m = n0 + n; (elim) Used terms: m, # bytes0, n
