Proof step 12 from proof lpt-leb-size-cleanup (previous step)

(lpf0 ≠ LP_FREE ⊃ mklp(0, 0, LP_FREE, m4);mklp(0, m3, LP_FREE, m4)) = mklp(m, m0, lpf, m1), lpt[n] = mklp(0, m3, lpf0, m4), m3 < m0, LEB_SIZE < m0, n < # lpt, m3 ≤ LEB_SIZE, ∀ n. n < # lpt → lpt[n].size ≤ LEB_SIZE ⊦

Heuristic nonsplitting cut applied rule cut formula

And closed the goal!

Rule argument

fma: lpf0 = LP_FREE
