| j ≤ 2 ^ n→i(m * n - 1), n ≤ n0 ⊦ m = 0, n = 0, j ≤ 2 ^ n→i(m * n0 - 1) |
⊦ j ≤ 2 ^ i ∧ i ≤ i0 ∧ 0 ≤ i → j ≤ 2 ^ i0
n ≤ n0, j ≤ 2 ^ n→i(m * n - 1) ⊦ m = 0, n = 0, j ≤ 2 ^ n→i(m * n0 - 1), j ≤ 2 ^ n→i(m * n - 1) ∧ n→i(m * n - 1) ≤ n→i(m * n0 - 1) ∧ 0 ≤ n→i(m * n - 1)
Used terms: j, n→i(m * n - 1), n→i(m * n0 - 1)
