Proof step 6 from proof booleanarray-get (previous step)

i→n(i) < # getarray(r, 0, st[r -- _length] .intval, st), okarray(r, boolean_type, st), i < st[r -- _length] .intval, r ∈ st, 0 ≤ i, 0 < st[r -- _length] .intval ⊦ (getarray(r, 0, st[r -- _length] .intval, st)[i→n(i)]) .boolval ↔ st[r -- i '] .boolval, r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
okarray(r, boolean_type, st), r ∈ st, 0 ≤ i, 0 < st[r -- _length] .intval, i < st[r -- _length] .intval ⊦ (getarray(r, 0, st[r -- _length] .intval, st)[i→n(i)]) .boolval ↔ st[r -- i '] .boolval, r = jvmref

Rule argument
