Proof step 6 from proof no-leading-zero (previous step)

int2bytes(bytes2int(i2b(0) ' + by ' + bytes)) = i2b(0) ' + by ' + bytes, 0 ≤ b2i(by) ⊦

User applied rule induction

And obtained the following new goals

Proof step 7:
int2bytes(bytes2int(i2b(0) ' + by ' + bytes)) = i2b(0) ' + by ' + bytes ∧ 0 ≤ b2i(by), ∀ by, bytes0. # bytes0 < # bytes → int2bytes(bytes2int(i2b(0) ' + by ' + bytes0)) = i2b(0) ' + by ' + bytes0 ∧ 0 ≤ b2i(by) → false ⊦ false

Rule argument

indvar: # bytes wfpred: <

Additional information

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