Proof step 2 from proof bytes2int-size-04 (previous step)

b2i(by) < 0, 2 ^ ((n→i(# bytes) + 1) * 8 - 1) + bytes2int(by ' + bytes) < 0 ⊦

User applied rule induction

And obtained the following new goals

Proof step 3:
b2i(by) < 0 ∧ 2 ^ ((n→i(# bytes) + 1) * 8 - 1) + bytes2int(by ' + bytes) < 0, ∀ by, bytes0. # bytes0 < # bytes → b2i(by) < 0 ∧ 2 ^ ((n→i(# bytes0) + 1) * 8 - 1) + bytes2int(by ' + bytes0) < 0 → false ⊦ false

Rule argument

indvar: # bytes wfpred: <

Additional information

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