Proof step 2 from proof ushort-max-05 (previous step)

256 ≤ us2i(sho) / 256, 0 < us2i(sho) / 256, 0 ≤ us2i(sho) / 256 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ i ≤ j ↔ ¬ j < i
Proof step 4:
¬ us2i(sho) / 256 < 256, 0 < us2i(sho) / 256, 0 ≤ us2i(sho) / 256 ⊦

Rule argument

seq: ⊦ i ≤ j ↔ ¬ j < i subst: [j, i] → [us2i(sho) / 256, 256] rotate: F spec: int-abs inst: name: ax-03

Additional information

Used terms: us2i(sho) / 256, 256
