Proof step 2 from proof bytes2int-first-pos (previous step)

bytes2int(by ' + bytes) < 0, 0 ≤ b2i(by) ⊦

User applied rule induction

And obtained the following new goals

Proof step 3:
bytes2int(by ' + bytes) < 0 ∧ 0 ≤ b2i(by), ∀ by, bytes0. # bytes0 < # bytes → bytes2int(by ' + bytes0) < 0 ∧ 0 ≤ b2i(by) → false ⊦ false

Rule argument

indvar: # bytes wfpred: <

Additional information

Used simplifier rules: <; (wellfounded) Used terms: # bytes
