Proof step 3 from proof is-encoded-size (previous step)

is-encoded(ns, buf) ⊦ # buf = # ns * ENCODED_NAT_SIZE

User applied rule induction

And obtained the following new goals

Proof step 4:
is-encoded(ns, buf), ∀ ns0, buf. # ns0 < # ns → is-encoded(ns0, buf) → # buf = # ns0 * ENCODED_NAT_SIZE ⊦ # buf = # ns * ENCODED_NAT_SIZE

Rule argument

indvar: # ns wfpred: <

Additional information

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