Proof step 38 from proof bin-heap-inv-write-other (previous step)

lpt[n] = mklp(m4, m5, lpf, m6), kar[m9] = key-index(natkey, n), 2exp-size(# kar), n < # lpt, m9 < # kar, m9 < m, heap-order(kar, m), no-dups-idx(kar, m), m ≤ # kar ⊦ lpf = LP_GROUP_NODES, m6 = m9, ∃ m0. m0 < m ∧ key-index(natkey, n) = kar[m0]
