Proof step 2 from proof bits2uint-not-zero (previous step)

bits2uint(bits) = 0, true ∈ bits ⊦

User applied rule induction

And obtained the following new goals

Proof step 3:
bits2uint(bits) = 0 ∧ true ∈ bits, ∀ bits0. # bits0 < # bits → bits2uint(bits0) = 0 ∧ true ∈ bits0 → false ⊦ false

Rule argument

indvar: # bits wfpred: <

Additional information

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