Proof step 2 from proof bits2bytes-len (previous step)

⊦ bits = [], # bits2bytes(bits) = (# bits - 1) / 8 + 1

User applied rule induction

And obtained the following new goals

Proof step 3:
true, ∀ bits0. # bits0 < # bits → true → bits0 = [] ∨ # bits2bytes(bits0) = (# bits0 - 1) / 8 + 1 ⊦ bits = [] ∨ # bits2bytes(bits) = (# bits - 1) / 8 + 1

Rule argument

indvar: # bits wfpred: <

Additional information

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