Proof step 24 from proof bin-heap-inv-write-other-fields (previous step)

kar[m9] = key-index(natkey, m7), lpt[m7] = mklp(m4, m5, lpf, m6), lpt[n] = mklp(m0, m1, lpf0, m2), lpt[n, mklp(n0, n1, lpf1, m2)][m7] = mklp(m3, m8, lpf2, m9), 2exp-size(# kar), m9 < # kar, m9 < m, n < # lpt, m7 < # lpt, heap-order(kar, m), no-dups-idx(kar, m), m ≤ # kar ⊦ m6 = m9
