Proof step 54 from proof challenge3a (previous step)

¬ (m2 < # ar1 ∧ ¬ bv0), bv0 ⊃ (ar1[m1] = ar1[n2] ∧ m1 ≠ n2 ∧ m1 < # ar1 ∧ n2 < # ar1) ; (∀ m1. m1 < m2 → (∀ n. m1 < n ∧ n < # ar1 → ar1[m1] ≠ ar1[n])), m2 ≤ # ar1, ar1 = ar, ∃ m, n. ar1[m] = ar1[n] ∧ m ≠ n ∧ m < # ar1 ∧ n < # ar1, ar[m1] ≠ ar[n2] ∨ m1 = n2 ∨ ¬ m1 < # ar ∨ ¬ n2 < # ar ⊦
