Proof step 4 from proof subset-band-01 (conclusion)

⊦ band(b2i(st[rk] .byteval), i) ≤ j ∧ rk ∈ st ∧ st ⊆ st0 → band(b2i(st0[rk] .byteval), i) ≤ j

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
band(b2i(st[rk] .byteval), i) ≤ j, rk ∈ st, st ⊆ st0, j < band(b2i(st0[rk] .byteval), i), band(b2i(st[rk] .byteval), i) < band(b2i(st0[rk] .byteval), i) ⊦
