Proof step 14 from proof suffix-lcp (previous step)

¬ (n0 = # ar ∨ n2 = # ar ∨ ar[n0] ≠ ar[n2]), m0 + 1 = lcp(ar, n0 + 1, n2 + 1) + 1, lcp(ar, n0, n1) ≤ m0, n0 ≤ # ar, n1 ≤ # ar, n2 ≤ # ar, suffix(ar, n0) < suffix(ar, n1), suffix(ar, n1) < suffix(ar, n2), ∀ ar0, n, n3, n4. m0 ≠ lcp(ar0, n, n3) ∨ ¬ lcp(ar0, n, n4) < lcp(ar0, n, n3) ∨ ¬ suffix(ar0, n4) < suffix(ar0, n3) ∨ ¬ suffix(ar0, n) < suffix(ar0, n4) ∨ ¬ n3 ≤ # ar0 ∨ ¬ n4 ≤ # ar0 ∨ ¬ n ≤ # ar0 ⊦

Proof step 13:
ar[n0] = ar[n2], n2 < # ar, n1 ≤ # ar, n0 < # ar, lcp(ar, n0, n1) ≤ lcp(ar, n0 + 1, n2 + 1), suffix(ar, n1) < suffix(ar, n2), suffix(ar, n0) < suffix(ar, n1), ∀ ar0, n, n3, n4. lcp(ar, n0 + 1, n2 + 1) ≠ lcp(ar0, n, n3) ∨ ¬ lcp(ar0, n, n4) < lcp(ar0, n, n3) ∨ ¬ suffix(ar0, n4) < suffix(ar0, n3) ∨ ¬ suffix(ar0, n) < suffix(ar0, n4) ∨ ¬ n3 ≤ # ar0 ∨ ¬ n4 ≤ # ar0 ∨ ¬ n ≤ # ar0 ⊦ n2 = # ar, n0 = # ar
