Proof step 2 from proof byte-not-max (previous step)

0 < i, 0 < b2i(by), 126 < b2i(by), b2i(by) + i < 128 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ i ≠ j -1 → (i < j ↔ i < j -1)
Proof step 4:
¬ b2i(by) + i ≠ 128 -1, 0 < i, 0 < b2i(by), 126 < b2i(by), b2i(by) + i < 128 ⊦
Proof step 7:
b2i(by) + i ≠ 128 -1, 0 < i, 0 < b2i(by), 126 < b2i(by), b2i(by) + i < 128 -1 ⊦

Rule argument

seq: ⊦ i ≠ j -1 → (i < j ↔ i < j -1) subst: [j, i] → [128, b2i(by) + i] rotate: F spec: int-basic1 inst: name: ls-rec
